WCDMA系统发射分集技术研究

Transmit Diversity Techniques for WCDMA Systems Research

发射分集技术是提高WCDMA通信系统中的下行链路容量和抗多径衰落干扰能力的有效技术,它利用发射天线空间分隔以获得相互独立的衰落信号的发射和接收,改善系统性能。本文介绍了WCD-MA系统中的开环和闭环两类发射分集技术,并对它们进行了分析和比较。

Transmit diversity technology in WCDMA system is one of the efficient technologies used in raising downlink capacity and capability of anti multipath fading interference.It can improve the performance of system by utilizing the independent fading signals emanating from spaced transmit antennas.This paper describes technologies of open loop transmit diversity and closed transmit diversity in WCDMA system and compare them.
