摘要
In this paper we research that using the precoding based on signal-to-leakage-and-noise ratio (SLNR) to reduce the inter-carrier interference (XI) of multi-user multiple-input multiple-output orthogonal frequency division multiplexing (MMO-OFDM system. Firstly, a model of MIMO-OFDM with precoding system is introduced Based on the model we get the algorithm of the precoding matrix. Through simulation and analysis, the ICI of MIMO-OFDM system with precoding is reduced, otherwise, the complexity of the receiver does not increase, so the method adapts to the downlink especially.
