Abstract

Based on the burst structure of TD-SCDMA system, a novel downlink SDM-JT model is put forward using the channel correlation between the uplink and downlink in TDD system. Meanwhile, by analyzing the features of wireless fading channel, the basic and improved SDM-JT algorithms are proposed. Simulation results show that the SDM-JT scheme can significantly improve the capacity and performance of TD-SCDMA system while the complexity of mobile station (MS) is sharply reduced
