本文围绕天线阵 Ｃ Ｄ Ｍ Ａ（ Ｃｏｄｅ Ｄｉｖｉｓｉｏｎ Ｍｕｌｔｉｐｌｅ Ａｃｃｅｓｓ，码分多址） 蜂窝无线通信系统，简介了无线信道、单时间与单空间处理的特点，综述了空时处理即矢量均衡技术，包括系统模型与空时过取样信号的结构特性，以及基于某些优化准则和结构特性的空时处理方法，论证了将空时处理嵌入 Ｉ Ｍ Ｔ２０００（ Ｉｎｔｅｒｎａｔｉｏｎａｌ Ｍｏｂｉｌｅ Ｔｅｌｅｐｈｏｎｅ２０００ ，２０００ 年全球移动电话） 的可行性． This paper focuses on the characteristics of wireless channel, single-time and single-space processing based on C D M A (Code-Division Multiple Access) cellular wireless communication system and summarizes the space-time processing, ie vector equalization, including System model and space-time over-sampled signal, as well as the space-time processing method based on some optimization criteria and structural characteristics, it is demonstrated that the space-time processing is embedded in I M T2000 (International Mobile Telephone2000, Global Mobile 2000 Phone) is feasible.
