The traditional direct sequence spread spectrum-code division multiple access communication system (DS-CDMA), the presence of multiple access interference (MAI) restricts the performance and capacity of the system. A better solution is joint detection technology, joint detection technology has become the third generation of mobile communication system, one of the key technologies. This paper studies the principle and complexity of several major joint detection techniques and compares the performance of various algorithms based on MATLAB simulation of TD-SCDMA uplink. Based on the ZF-BLE algorithm, Improvement of joint detection technology
