| 摘 要： | TD—SCDMA系统中，采用波束赋型技术在很大程度上降低了多址干扰，改善了通信质量。通过研究移动终端在使用天线阵列情况下的性能提升情况，提出了双天线自适应阵列应用于终端的方案。分析了不同情形下的双天线阵列的性能，并且基于特定的多径衰落信道环境对改进的NLMS—C算法和其他2种不同的自适应算法进行了仿真比较。仿真结果表明，采用双天线阵列移动终端系统能获得更好的性能。

| Abstract: | The muhi-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 termi- nal can achieve better performance.. |
