摘要
OFDM(Orthogonal Frequency Division Multiplexing)和MIMO(Multiple-Input-Multiple-Output)技术是解决未来宽带无线通信系统中多径衰落信道和带宽效率两大技术难点的关键技术,文章研究了MIMO—OFDM系统及常用的空时编码方式的性能特点,并对空时编码技术与MIMO—OFDM系统相结合对通信系统性能的影响作了深入的研究。
OFDM and MIMO are two key techniques to solve the problems that are the bandwidth efficiency and multipath fading channel in future broadband wireless communication system. Paper analyses performance of OFDM and MIMO system and space-time coding. Paper does further study on effects in performance of communication system for combining space-time coding with MIMO-OFDM system..
