摘　　要：提高频谱利用率是当前和今后无线通信的一个重要问题,多输入多输出(MIMO)和空时编码技术越来越引起人们的重视。介绍了MIMO系统及其D_BLAST和V_BLAST算法,并分别介绍了空时格码和空时分组码及其编码和解码方法。最后给出了MIMO与空时码的研究动态。To improve the spectrum efficiency has been an important issue to wireless communication recently. The future MIMO system and space time coding technique have been researched by more and more scholars. This paper introduces the MIMO system and the responding arithmetic D_BLAST & V_BLAST, the space-time trellis code and space time block code as well as the responding coding and decoding technology. At last, the developmens of MIMO and space time code are pointed out.
