Research on the joint detection in TD-SCDMA system

Joint detection is one of the key technologies of TD-SCDMA system, which leads to TD-SCDMA to achieve high data rate services. It can suppress multiple access interference and inter symbol interference, and recover data symbols of the active users. In this paper, the theoretical analysis of zero-forcing block linear equalization (ZF-BLE) and minimum mean square error block linear equalization (MMSE-BLE) are investigated. The performance of ZF-BLE and MMSE-BLE is compared by computer simulation.
