Combined spatial filter and joint detector

In CDMA system, co-channel interference (CCI) includes intracell multiple-access interference and intercell interference. In TD-SCDMA mobile systems, intracell MAI can be eliminated by joint detection. In this paper, one approach combined joint detector and spatial filter which can eliminate both intercell and intracell interference is proposed. Moreover, this approach can be implemented with low computational complexity. Link simulation shows that the performance of TD-SCDMA systems with this approach is better than joint detection with antenna diversity.
