Waghmare Electronics and Communication Engineering Department, Dr. Babasaheb Ambedkar College of Engineering and Research, Nagpur (India) Prof. Dr. Shripad P. Mohani Electronics and Telecommunication Engineering Department, College of Engineering, Pune (India) ABSTRACT Orthogonal frequency division multiplexing (OFDM) is a robust and effective multicarrier transmission technique for high speed communication in wireless mobile environment and applications. A major challenging issue in application of OFDM is its high peak to average power ratio (PAPR). Selective mapping (SLM) is one of the promising techniques which offer distortionless PAPR reduction at the cost of bandwidth efficiency and computational complexity. In this work, SLM is modified by using new phase sequences, which are combinations of Centering matrix along with Hadamard and Riemann matrices. Simulation results show that the proposed phase sequences offer improved PAPR reduction and thus outperform some of the previously proposed techniques. Keywords: Centering operation, Multicarrier Systems, Orthogonal Frequency Division Multiplexing (OFDM), Peak to average power ratio (PAPR), Selected Mapping (SLM) I. INTRODUCTION Orthogonal Frequency Division Multiplexing is extensively implemented in various high speed wireless communication standards because of its favorable properties such as high spectral efficiency, robustness to channel fading, capability of handling multipath fading and immunity to impulse interference. Interestingly, OFDM is a combination of modulation and multiplexing. ne major limitation is its large Peak to Average Power Ratio (PAPR). These large peaks cause saturation in power amplifiers at the transmitting end, leading to inter-modulation among the subcarriers, which causes an increase in the out of band (OOB) energy of the spectrum. Hence, to design a cost effective and robust system, it is highly desirable to reduce the PAPR. Reduction of PAPR is a major challenge for which many techniques are proposed in the literature. 207

The proposed phase sequences show enhanced performance with respect to PAPR reduction. II. ORTHOGONAL FREQUENCY DIVISION MULTIPLEXING (OFDM) The multicarrier modulation techniques employ several carriers, within the allocated bandwidth, to convey the information from source to destination. Each carrier may utilize one of the several available digital modulation techniques (BPSK, QPSK or QAM) [1]. Generally, an OFDM signal can be represented as: cሺtሻ = ∑ିଵ ୬ୀ s୬ ሺtሻ sinሺ2πf୬ tሻ Where: c(t) s୬ ሺtሻ (1) : OFDM signal representation in Time Domain : Symbols mapped to chosen constellation (BPSK/QPSK/QAM) f୬ : Represents the orthogonal frequencies Equation (1) can be thought of as an Inverse Fast Fourier Transform (IFFT) where ‘N’ is the size of IFFT. The Fourier transform breaks a signal into different frequency bins by multiplying the signal with a series of sinusoids. Since the OFDM signal is in time domain (refer (1)), IFFT is the appropriate choice to use at the transmitter. To acquire the original transmitted signal, FFT is performed at the receiver side [2]. III. PEAK TO AVERAGE POWER RATIO (PAPR) The mathematical representation of PAPR of an OFDM signal can be given as – PAPRሼcሺtሻሽ ൌ మ ౣ౮ ರರొషభ│ୡሺ୲ሻ│ మ (2) ቂ│ୡሺ୲ሻ│ ቃ ଶ Where E ቄ│cሺtሻ│ ቅ denotes the expectation of c (t). PAPR can be expressed in ‘dB’ as follows. PAPR (dB) = 10logଵ PAPR ୡሺ୲ሻ (3) Some of the distortion based techniques for PAPR reduction include clipping and filtering, commanding, coding. Selective mapping (SLM), partial transmit sequence (PTS), tone reservation, tone injection, constellation extension are Distortion less Techniques for PAPR reduction. SLM technique improves PAPR statistics of an OFDM signal significantly without any in-band distortion and out-of-band radiation. The selection of proper phase sequences to achieve good PAPR reduction is very important in the SLM technique [3]. IV. SELECTED MAPPING TECHNIQUE (SLM) SLM method is a distortion less probabilistic technique for PAPR reduction. This technique is called distortion less because the quantity with which the actual signal is altered is sent as side information [4] In this method, the original modulated OFDM data block is multiplied element by element with phase sequences; 208

Reverse operation should be performed at the receiver to obtain the original data block [3], [4]. Fig. 1 Block diagram of the SLM scheme in OFDM V. EXISTING PHASE SEQUENCE FOR SLM The Matrices like Hadamard and Riemann are very popular phase sequence generating matrices for SLM techniques [5][6]. A newly introduced matrix called Centering matrix has given so far the best performance as compared to the conventional matrices. [7] 5.1 Centering matrix The centering matrix is a symmetric and idempotent matrix, which when multiplied with a vector has the same effect as subtracting the mean of the components of the vector from every component [7]. The structure of centering matrix (C୬ ) is given by C୬ ൌ I୬ െ 1 O n ୬ Where, I୬ - is the n-by-n identity matrix O୬ - is an n-by-n matrix of all 1's 209

PROPOSED PHASE SEQUENCE In this experimentation, combinations of the Centering matrix with the special matrices like Hadamard and Riemann has been explored. The formulation of the new phase sequence generating Matrices is explained below. 6.1 Centering of Hadamard and Riemann Matrices Centering operation on a data matrix is done by multiplying the particular matrix with the Centering matrix. The values of the newly formed data matrices get close to their respective mean values after the centering operation [8]. Centered Hadamard matrix: Centered Riemann matrix: Where, H୬ - Hadamard matrix (n-by-n) C୬ - Centering matrix (n-by-n) C୦ = C୬ * H୬ C୰ = C୬ * R ୬ 6.2 New Phase Matrix In the quest of finding new phase sequences, another combination of centering matrix with the special matrices is formed. The proposed phase sequences are generated by performing elementby-element multiplication of Centering matrix with Hadamard and Riemann matrices. This combination delivers a new set of phase sequences, which offers better results than the other matrices considered in this experimentation. As there is element-by-element multiplication between the two matrices, it has fewer computations than the Centered matrices explained earlier. Instead of using any random sequence as phase sequence, a combination of two standard matrices is being used in this work. This matrix combination can also be generated at the receiver, leading to a reduction in side information, as only the row index number can be sent as side information. Modifications in the existing SLM scheme are introduced by the newly proposed phase sequences. New Hadamard Cୡ୦ሺ୬ୣ୵ሻ = C୬ .* H୬ New Riemann Cୡ୰ሺ୬ୣ୵ሻ = C୬ .* R ୬ VII. SIDE INFORMATION The side information is the most important aspect of the SLM technique. Thus, it is highly essential to save the side information from getting corrupted while it travels through the channel. In this experimentation, the side information is sent in the form of row index or row number of the phase sequence generator matrix, which provides the least PAPR for a particular OFDM symbol [7] [9]. BCH coding is done on the set of side information collected for all the corresponding OFDM symbols. The Bose, Chaudhuri and Hocquenghem (BCH) codes form a large class of powerful random error-correcting cyclic codes. For any positive integers mሺm 3ሻ and tሺt ൏ 2୫ିଵ ሻ, there exists a binary BCH code with the following parameters: Block Length: n ൌ 2୫ െ 1 Number of parity-check digits: n െ k mt Minimum distance: d୫୧୬ 2t 1 This code is capable of correcting any combination of ‘ ’ or fewer errors in a block of n ൌ 2୫ െ 1 digits. BCH code of size (7, 4) is used in this experimentation. 210

BER plots for different phase matrices The Centered Hadamard performs better than original Hadamard and Centered Riemann provides more PAPR reduction than the original Riemann matrix. The proposed New Riemann matrix shows near elimination of peaks from the OFDM signal. PAPR reduction of around 8 dB to 8.5 dB is obtained. Centering matrix shows PAPR reduction more than Riemann (refer Fig. 2) [7]. From this work, it can be stated that the proposed new Riemann matrix performs even better than the Centering matrix. The proposed new Riemann matrix was tested for its PAPR performance on a fixed input bit stream taking different M-QAM constellations and IFFT sizes. Four times oversampling of the modulated symbols is performed before taking IFFT. Following table demonstrates the results. An OFDM symbol is generated using the combinations of M-QAM and IFFT and minimum PAPR (dB) is found. 211

PAPR(dB) 0.1643 0.2000 0.0629 0.0613 0.0250 0.0212 It can be observed from Table. II, as the IFFT size increases, the PAPR of the OFDM signal reduces by a significant value. For the same IFFT size, if M-QAM constellation is changed, PAPR of the particular signal does not undergo any major change. The OFDM symbols are transmitted through AWGN channel i.e. AWGN noise is added to the transmitted signal. The robustness of a communication system is determined by the performance of the receiver. The BER vs SNR performance for various phase matrices is compared to that of the unmodified OFDM in Fig. 3. The unmodified original OFDM and SLM with Hadamard and Centering matrix present almost the same performance. BER of the system with proposed new Riemann matrix can be reduced by applying high SNR. As trade-off is usually experienced in communication, here also a trade-off between BER and PAPR performance in the proposed scheme is seen. IX. CONCLUSION In this paper, a modification in the phase sequence for conventional SLM scheme is proposed. The proposed new Riemann phase sequence shows PAPR reduction to a greater extent as compared to that obtained by using other phase altering matrices. It indeed outperforms the already proposed Centering, Riemann and Hadamard matrices, in terms of amount of PAPR reduction in OFDM. The side in formation sent along with the individual OFDM data blocks is the row index number of the selected phase sequence instead of sending the whole of the phase sequence. Thus the bandwidth efficiency and the power consumption of the system is enhanced. However, the proposed phase sequences cause an increase in bit error rate (BER). To reduce the BER, highly powerful error control codes (have the effect of increase in bandwidth) can be used. Use of higher transmit power can be another alternative for BER reduction. So, either of the two resources, signal-to-noise ratio (SNR) or bandwidth, can be used to reduce the BER.
