摘要 预编码是一种应用于发射端以达到抑制多用户间干扰的预均衡方法。MIMO预编码技术可有效防止误码扩散,大大降低接收端的复杂度。该文对多用户MIMO系统预编码的几种算法进行了研究,分析了其各自的优缺点,并提出了改进方法。其中包括迫零(ZF)线性预编码、块对角化(BD)线性预编码、最小均方误差(MMSE)线性预编码及信漏比(SLR)线性预编码。 Pre-coding is a pre-equalization technique that suppresses the interference between users at the transmittec.MIMO pre--coding technology can effectively prevent error diffusion,greatly reduce the complexity of the receiving end.In the paper, several algorithms of multi--user MIMO system pre-coding have been studied,analyzed its own advantages and disadvantages,and put forward some improvement methods.Including the zero forcing(ZF)linear pre--coding,block diagonalization(BD)linear pre-- coding, the minimum mean square error(MMSE)linear pre-coding and signal leakage ratio(SLR)linear pre-coding.
