Abstract
TD-SCDMA is one of the 3G wireless communication standards accepted by ITU and 3GPP. TD-SCDMA system has employed joint detection algorithms in downlink to improve the performance. As an important part of joint detection algorithm, active codes detection algorithm has large effect on the performance. In this paper, we propose a channel estimation aided active codes detection algorithm. Theory analyses and simulation results show that the proposed algorithm has better system performance compared with conventional algorithm.
