Xin-bo Luo, Xianzhong Xie, Yuan Feng, Yang Liu · 2007
This paper investigates an optimization transmission algorithm in MIMO multiuser downlinks and applies it in TD-SCDMA. A generalized optimization criterion of the JT total transmit signal and optimization of spatial characteristics of the total transmit signal in the case of the omnidirectional uniform distribution of direction of departure are introduced respectively, which can directly eliminate intersymbol interference and intracell multiple access interference. Simulation proves its performance in the TD-SCDMA system.
