Abstract : Current trends in the development of high-data-rate wireless systems focus on the integration of orthogonal frequencydivision multiplexing (OFDM) and multiple-input?multiple-output (MIMO).The combination of OFDM and the Multiple-InputMultiple-Output (MIMO) technique represents a promising candidate for future broadband wireless systems. This paper addresses the Inter Carrier Interference (ICI) issue in multiuser MIMO-OFDM systems operating in time-varying frequency selective channel environments.In our proposed method precoding based on signal-to-leakage-and-noise ratio (SLNR) is considered.In this paper model using precoding in MIMOOFDM is introduced.Based on the model algorithm for precoding matrix is developed.Simulation results confirms reduction in ICI without increasing complexity of a system.
