TD-SCDMA系统最重要技术特征是智能天线技术。本文提出了基于时延和角度扩散及天线结构的时空间信道信道模型。在此基础上研究了下行链路智能天线的波束加权方法。
The most important technical feature of TD-SCDMA system is smart antenna technology. This paper presents a time-space channel model based on delay and angle spread and antenna structure. Based on this, the beam weighting method of downlink smart antenna is studied.
