12. TD-SCDMA Standard
• ITU acceptation in 1998 and approval in
WRC2000
• Harmonization with UMTS on CN and
architecture
• Included in 3GPP from R’4 (2001) to R’7(now)
• Specifications fixed and mature for R’4/5,
• New features and technologies introduced
after R’5 and LTE
• Has the characteristics for Beyond 3G

The advantages of SA
Minimizing inter/intra-cell interference
Effective TX power
Improved receiving sensitivity
Increased coverage and capacity
Reduced Node B cost for RF

18. Joint Detection
MAI is the major interference in the CDMA system.
Traditional signal processing to deal MAI as noise
JD optimizes the specific user signal, including:
Specific user signal channel code
Specific training sequence
Process all the signals in parallel to eliminate MAI
