摘　　要：PHS系统由于其体积小,功耗低等优点,在很多大城市得到了广泛应用。但同时由于其覆盖范围小等缺陷,限制了PHS系统进一步的应用。由于智能天线技术具有很高的覆盖范围,所以提出了一种在PHS无线通信系统中实现智能天线接收技术的方法,并建立了一套完整DSP硬件仿真平台。同时基于上述硬件仿真平台对智能天线接收技术中的自适应算法的接收性能及实时性进行了分析比较,并给出了实验结果。PHS system is used in many big cities for such as small size and low power, but the cover ranges of PHS system are too small to be popularized further. Because smart antenna technique can obviously overcome this shortcoming, a smart antennas receiver for PHS wireless Communication system and a complete set of DSP hardware simulation platform are set up. Then an analysis and comparison of the performance of the receiver, including the performance of the real-time adaptive algorithm of smart antennas receiver based on simulation platform are presented. Also, the results of the experiment are given.
