Abstract: The dissociative processing of time and space used in TD-SCDMA system by the algorithm of smart antenna and joint detection in series. An algorithm based on the integrated processing of space-time realized by the combination of smart antenna and joint detection is designed, which not only reserves the merits of the two techniques, but also makes the better performance of TD-SCDMA system. At last, the BER curves of system obtained by the simulation of the two processing methods in the same condition are presented and the complexity of the union algorithm is analyzed, which proposed a reference to the feasibility of this algorithm.
