Error Control and performance Analysis of MIMO-OFDM Over Fading ChannelsIOSR Journals
ABSTRACT: Multiple Input Multiple Output is a wireless technology that uses multiple transmitters and
receivers to transfer more data at the same time. Orthogonal Frequency Division Multiplexing, an FDM
modulation technique which splits the signal into multiple smaller sub-signals that are then transmitted
simultaneously at different frequencies to the receiver. OFDM technique spreads the data over number of
carriers which are at specific predefined frequencies. This reduces or eliminates the ISI. Forward error
correction or channel coding is a technique used for controlling errors in data transmission over unreliable or
noisy communication channels. The objective of our proposed paper is to implement the FEC into the MIMO
OFDM systems and its performance is analysed by using MATLAB over different fading channels. For
modulation it employs M-QAM which combines both ASK and PSK thereby enabling several bits to be
transmitted per symbol. The performance of MIMO-OFDM system is evaluated by BER Vs SNR when the bits
propagates through the different fading channels.
Keywords– OFDM, MIMO, QAM, FEC, BER.

After reading the Top 14 IoT Trends to Emerge in 2023 article, you will learn about what the 14 IoT Trends will be happening.
What is IoT?
The Internet of Things (IoT) is a system of connected devices, digital machines, and users with unique identifiers and network transportability that eliminates the need for human-to-human or human-to-machine interaction.
IoT is an important part of the new generation of information technology. Unlike the Internet, the main application objects of IoT are some physical devices, such as vehicles, home appliances, buildings, etc.
By embedding electronic software, sensors and some network connection devices in these physical devices, the exchange of data between devices can be realized, thus establishing a set of interconnected networks.
According to statistics, more than 43 billion devices are currently expected to be connected to the IoT worldwide, which will generate, share, collect and help people use data in a variety of ways.
The 14 most important IoT trends
Here are the 14 most important IoT trends that will change the world in 2023.
NB-IoT WiKi
NB-IoT (Narrowband IoT) is a low-power technology designed for Internet of Things (IoT) applications and other low-data rate communication requirements.
It uses narrowband radio spectrum and advanced power management techniques to efficiently utilize the available spectrum and extend the battery life of IoT devices.
NB-IoT is based on LTE cellular wireless technology and has been standardized by the 3rd Generation Partnership Project (3GPP) as the global wireless communication standard for IoT applications.
LoRa Alliance Extends LoRaWAN Standard to Support the Internet of Things Applications
The LoRa Alliance Extends LoRaWAN Standard to Support IoT Applications by adding TS013-1.0.0, an application programming interface (API) for application payload decoder-encoders (codecs).
The LoRa Alliance reported it on October 25, 2022. The consortium is the global association supporting the Internet of Things (IoT), Low Power Wide Area Network (LPWAN) open LoRaWAN standard.

After the read, you will know, what is a private 5G network and how a 5G private network works.
What is a private 5G network?
A private 5G network is a wireless network that uses the 5G mobile networking standard and is owned and operated by a single organization, rather than a commercial telecommunications provider. Private 5G networks are often set up for use by a specific business or organization and can be used to provide secure and reliable wireless connectivity for a variety of applications, such as industrial automation, remote monitoring, and more.
Unlike public 5G networks, which are available to anyone with a compatible device, private 5G networks are typically only accessible to authorized users.
A private 5G network is a local area network (LAN) that uses 5G technology to create a private network with unified connectivity, optimized services, and a secure way of communicating within a specific area.
The concept of a Private Network has been around for a long time. In contrast to public networks, which are primarily intended for the general public, private networks exist primarily to address specific industries/needs. The difference between a public network and a private network is that a public network serves the general public, while a private network serves a specific audience.
This article comprehensively explains low-power wide area network (LPWAN) technology for IoT.
IoT communication technologies are divided into two categories: short-range wireless LAN and low-power wireless WAN (LPWAN), Bluetooth, Wi-Fi, ZigBee, etc. are belong to short-range wireless LAN.
LPWAN is mainly used in long-range, low-bandwidth, low-power, and many connection needs of IoT application scenarios, the hottest LoRa in the market in recent years is the most representative technology in LPWAN. LoRa is the most representative technology in LPWAN.
Non-cellular low-power IoT technology solves the problem of large-scale and wide-coverage network connectivity for IoT applications, which makes up for the shortage of traditional cellular technology and promotes the application of IoT and large-scale deployment. Low-power wide-area networks will carry the burden of communication network economies of scale in the future IoT era.
What is wireless 5G LAN?
5G LAN is a LAN built in a 5G network, through which a LAN with mobility can be assembled to meet production and office needs. 5G LAN has the benefit of cross-territory mobility, so even if two people are thousands of miles apart, they can still set up a LAN to achieve Layer 2 and 3 interoperability.
Simply put, 5G LAN uses 5G technology to group and build groups of terminals to form a LAN network. When using 5G cell phones, have you ever noticed that even if you and your friends are close together (even face to face), your phone cannot search each other? You can communicate with each other because the data flow to the carrier or Internet service provider's server around the circle.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

13 Common IoT Communication Technologies
Today, we talk about the wired and wireless IoT Communication Technologies, the simple 13
common communication technologies in IoT.
We have compiled and summarized the commonly used wired and wireless communication
methods of IoT for future reference.
Wired part of the IoT communication technologies
RS232 in the IoT communication Technologies
Communication method: full-duplex communication (can send and receive data at the same
time)
Communication distance: the standard value is 50 feet, in fact, it can only be used at about 15
meters
Transmission method: asynchronous transmission
Transmission rate: 20Kbps
Description: One of the mainstream serial communication interfaces, commonly used are DB9
and DB25. The transmitted digital quantity adopts negative logic and is symmetrical with the
ground (logic 1: -3 to -15V, logic 0: +3 to +15V) ). It can only be used for point-to-point
communication.
RS485 in the IoT communication Technologies
Communication method: half-duplex communication (cannot send and receive data at the same
time)

Contact Person: Coco Lu coco@ctrfantennasinc.com (+86)13412239096
Communication distance: The farthest can reach about 1200 meters, but its transmission rate is
inversely proportional to the transmission distance. Only the transmission speed below 100Kb/s
can reach the maximum communication distance. If you need to transmit longer distances, you
can use it. Following Up to eight relays can be added, which means that theoretically, the
maximum transmission distance of RS485 can reach 10.8 kilometers
Transmission method: asynchronous transmission
Transmission rate: 10Mbps
Illustrate:
One of the mainstream serial communication interfaces does not need to detect the signal
relative to a certain reference point. The system only needs to detect the potential difference
between the two wires.
It has a strong ability to resist common-mode interference. Logic "1" is represented by the
voltage difference between the two lines as +(2~6)V, and the logic "0" is represented by the
voltage difference between the two lines as -(2~6) V said.
Supports multi-point data communication; And the network topology generally adopts a
terminal-matched bus-type structure, that is, a bus is used to connect each node in series. Ring
or star-shaped networks are not supported. It supports up to 32 nodes.
RS422 in the IoT communication Technologies
Communication method: full-duplex communication (can send and receive data at the same
time)
Communication distance: about 1200 meters
Transmission method: asynchronous transmission
Transmission rate: 10Mbps
Note: Separate sending and receiving channels are used, so there is no need to control the data
direction. Support multi-point data communication, up to 10 nodes.
M-BUS in the IoT communication Technologies
Communication method: half-duplex communication (master-slave)
Communication distance: up to 3600 meters
Transmission method: asynchronous transmission
Transmission rate: about 5kb/s
Note: It uses the caller/response method to communicate, that is, only after the central station
(Master) sends an inquiry, the slave station (Slave) can transmit data to the master station.
Bus-type topology.
When the master station sends a logic "1" to the slave station, the bus voltage Vmark≤42V, and
when a logic "0" is sent, the voltage drops by more than 10V, and drops to Vspace≥12V;
When the slave station sends a logic "1" to the master station, the current drawn by the slave
station is Imark≤1.5mA. When a logic "0" is sent, the slave station will add a pulse current of
11-20mA to Imark to form an Ispace.

Transmission method: synchronous transmission
Transmission rate: different according to different schemes
Illustrate:
Power line carrier communication is a communication method in which high-frequency carrier
signals transmit information through high-voltage or low-voltage power lines. The power line
causes high cuts to the carrier signal.
When the load on the power line is heavy, the line impedance can reach below 1 ohm, resulting
in a high reduction in the carrier signal. In practical applications, when the power line is empty,
the point-to-point carrier signal can be transmitted up to several kilometers. But when the load
on the power line is heavy, only tens of meters can be transmitted.
The Wireless part of the IoT communication Technologies
Zigbee in the IoT communication Technologies
Communication frequency band: license-free frequency band. Use Industrial Scientific Medical
(ISM) frequency band, 915MHz (U.S.), 868MHz (Europe), 2. 4GHz (Global)
Communication distance: The transmission range is generally between 10 and 100m, after
increasing the transmission power, it can also be increased to 1 to 3km. This refers to the distance
between adjacent nodes. If through the relay of routing and communication between nodes, the
transmission distance will be farther
Low power consumption
Transmission rate: 20~250kbps
Description: Short-range, high-reliability, low-complexity, low-power, low-data-rate, and low-cost
wireless network technology is mainly used for short-range wireless connections. Within the
entire network, each ZigBee network data transmission module can communicate with each
other. Each ZigBee network node can not only be a monitoring object by itself, for example, the
connected sensor can directly collect and monitor data, but also can automatically transfer to
other data from the network node.
In addition, each ZigBee network node can also wirelessly connect to multiple isolated sub-nodes
that do not undertake the task of network information transfer within the range of its own signal
coverage.
Bluetooth in the IoT communication Technologies

Transmission rate: Bluetooth 2.0 speed: 1.8M/s, Bluetooth 3.0 speed: up to 24M/s, Bluetooth 4.0
speed: 24M/s
Illustrate:
Bluetooth uses frequency hopping technology to divide the transmitted data into data packets,
which are respectively transmitted through 79 designated Bluetooth channels.
The bandwidth of each channel is 1 MHz. Bluetooth 4.0 uses 2 MHz spacing and can
accommodate 40 channels. The Bluetooth master device can communicate with up to seven

and the slave device can also be converted to the master device.
WI-FI in the IoT communication Technologies
Communication frequency band: License-free
Communication distance: depends on the router
Power consumption: larger
Transmission rate: 54Mbps
Illustrate:
The wireless network in the category of wireless local area network refers to "wireless
compatibility certification", which is essentially a commercial certification and also a wireless
networking technology. The common one is a wireless router, so the radio wave coverage of this
wireless router is effective the range can be networked by a Wi-Fi connection. If the wireless
router is connected to an ADSL line or another Internet line, it is also called a hotspot. The data
security of WIFI is relatively poor.
NB-IoT in the IoT communication Technologies
Communication frequency band: use the frequency band number defined by LTE (according to
the operator)

NB-IoT is built on a cellular network and only consumes about 180KHz of bandwidth, and can be
directly deployed on a GSM network, UMTS network, or LTE network.
NB-IoT is an emerging technology in the IoT field, which supports the cellular data connection of
low-power devices in the wide-area network. It is also called a low-power wide-area network
(LPWAN).
Supports efficient connection of devices with long standby time, and high network connection
requirements. At the same time, it can provide very comprehensive indoor cellular data
connection coverage. Long-distance, low power consumption, and half-duplex communication
are its characteristics.

Illustrate:
LoRa is monopolized by the US company SEMTECH's exclusive proprietary technology, and the
terminal and gateway chip IP patents are exclusively controlled by SEMTECH. The biggest feature
is that it can travel farther than other wireless methods under the same power consumption
conditions, achieving low power consumption and long-distance Unified, it is 3-5 times longer
than the traditional radio frequency communication distance under the same power

Transmission rate: It depends on factors such as the length of the code, the data transmission
rate of the carrier, the reading and writing distance, the carrier frequency between the carrier
and the antenna, and the modulation technology of the data transmission. The transmission rate
varies with the types of products in actual applications.

NFC is developed on the basis of RFID. In essence, NFC is not much different from RFID. Both are
based on the signal transmission between two objects that are geographically close.
NFC technology adds a point-to-point communication function, which can quickly establish P2P
(point-to-point) wireless communication between Bluetooth devices. NFC devices find each other
and establish a communication connection.
The two devices of NFC communication are peer-to-peer, while the two devices of RFID
communication are in a master-slave relationship. NFC is very safe because of its communication
distance.
