Linear multi-user detection algorithm and performance simulation for TD-SCDMA system Vol. 13 No. 2 Journal of Chongqing U n iversity of Posts and Telecomm un ication s Jun. 2001Article Number: 1004 5694 ( 2001) 02 0001 04Linear multi-user detection algorithm and performance simulation for TD-SCDMA system GAO Baogui, MIAO Dan, XIONG Simin, XIE Xianzhong ( Chongqing U n iversity of Posts and Telecomm un ication s, Chongqing 400065)Abstract: In TD-SCDMA system, the existence of MAI and near-far effect has a great influence on the system performance. The traditional detector treats MAI as noise and cannot eliminate the influence of MAI and near-far effect. Several different detection algorithms in multi-user detection technology over multipath Rayleigh fading channels are discussed, and these different algorithms are simulated and compared.
