摘要 研究V-BLAST MIMO MC-CDMA下行系统。提出了一种对每个子载波进行V-BLAST译码的非线性算法,对不同天线数、用户数情况进行了系统的仿真和分析,并对V-BLAST译码的线性和非线性算法进行了系统仿真比较。 This paper investigates V - BLAST MC - CDMA down link. A V - BLAST detector per subcanier is proposed for MIMO MC - CDMA system in this paper and the system performance with various numhers of V - BLAST antennas and users for such a system is evaluated through simulations.
