差分空時編碼CDMA系統(tǒng)的多用戶接收機設(shè)計
Multiuser Receiver Design for Differential-Space-Time-Coded CDMA Systems

摘要: 利用碼分多址和互滿正交設(shè)計，該文針對多天線系統(tǒng)提出了非相干空時傳輸方案。它可支持滿分集通信，并能有效抑制多用戶干擾。基于平坦Rayleigh衰落信道，給出了差分解相關(guān)接收機，它不僅隔離了不同用戶的檢測，而且使不同數(shù)據(jù)符號的譯碼彼此獨立。

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. -
