摘要 MIMO系统与的单天线系统相比,在系统容量与传输可靠性两方面都得到了极大的提高,是下一代无线通信的主要技术之一。其中,空间复用码是提高MIMO系统容量的一种空时编码方案,但在病态信道下,其复用性能受到较大限制,可通过发送端预编码来改善空间复用码的性能。但是,随着无线频谱资源的紧张,传输全部的反馈信息显得不切实际。之前各类文献对基于信道奇异值分解的方法,提出了很多码本的设计方法。而本文针对一种均匀信道分解的MIMO预编码方案,提出了一种双码本的设计方法。 MIMO(Multi-input multi-output)wireless communications have large improvement in system capacity and reliability. SM( Spatial Multiplexing) is a method to explore MIMO capacity. However, SM is sensitive to ill-conditioned channel matrix. Precoding can improve the resilience of SM at the expense of the full channel knowledge-which is often not realistic. We find a codebook design method for uniform channel decomposition MIMO communication: double codebooks.
