Abstract

According to the features of TD-SCDMA system, a novel multi-antenna pre-processing model and algorithm is proposed. Meanwhile, the more precise uplink channel estimation and downlink channel prediction are put forward for TD-SCDMA system to improve the performance of basic multi-antenna pre-processing algorithm. Simulation results show that: by using the proposed multi-antenna pre-processing technology, the capacity and performance of TD-SCDMA system is significantly improved. Meanwhile, the improved multi-antenna pre-processing algorithm performs better than the basic algorithm under fast varying channel condition.
