摘要: 利用码分多址和互满正交设计，该文针对多天线系统提出了非相干空时传输方案。它可支持满分集通信，并能有效抑制多用户干扰。基于平坦Rayleigh衰落信道，给出了差分解相关接收机，它不仅隔离了不同用户的检测，而且使不同数据符号的译码彼此独立。

Abstract: Based on code division multiple access and amicable orthogonal design, a non-coherent space-time transmission scheme is proposed for multiple-antenna systems, which allows full-diversity communication and is resistant to multiuser interference. Then a differ-ential decorrelative receiver is given for flat Rayleigh fading channels, which decouples not only the detection of different users but also the decoding of different data symbols. -
