Abstract :
In this paper, a dual-antenna receiver adaptive algorithm AMSNR in TD-SCDMA terminal is proposed. The dual-antenna receiver combines the received signal from different antennas with optimized weights according to the maximum signal-to-noise ratio (MSNR) criteria. Simulation results show that this algorithm can achieve better performance than conventional receiver with single antenna, and comparing to space time joint detection (ST-JD), the presented algorithm can decrease the computation complexity greatly.
