Abstract: The multi-access interference and quality of communication system can be greatly improved by beam forming technology when the smart antenna is adopted.This paper investigates the performance improvement given by a multi-antenna receiver on a mobile terminal, and a link level simulation scheme is presented based on TD-SCDMA system.The performance of dual smart antenna under different circumstances is analyzed, and the improved NLMS-C algorithm and two different adaptive algorithms are compared under the specifically modeled multipath fading channel.The simulation results show that a dual-antenna arrangement on a mobile terminal can achieve better performance.
