Xiao Xiang Shen, Hui Zhi, Shi Xiang Shao · Advanced materials research · 2011
CDMA system is the interference-restricted system, In the TD-SCDMA trunking system, using more than one scrambling in a cell introduces multiple access interference (MAI).This paper analyzes improving the performance of MMSE and PIC Detectors in TD-SCDMA trunking system with different level MAI. It can be seen from the simulation result, the joint detection algorithm can improve the performance of downlink for TD-SCDMA trunking system, and it also can help to keep the stability of this system.
