摘　　要：空时信道模型在智能天线系统性能的评估中是非常重要的。对智能天线系统中常用的空时信道模型做了详细的介绍 ,分析了每种模型的特点和每种模型所适用的具体情况。对其中得到广泛使用的GBSB模型具体分析了到达角、时延概率函数以及Doppler谱 ,并做了计算机模拟 ,认为Clarke模型是其中的一个特例。Space-time channel models are very important in evaluation of smart antenna system. In this paper, several space-time channel models that are often used in smart antenna system are presented and the properties of each model are analyzed. At the same time, the situations for each model are discussed. DOA, time delay and Doppler spectrum are discussed specially, while computer simulation is also done. Clarke model is considered as a special one.
