In the proposed method, a genetic algorithm is used to find the optimum coefficients of the pre-coder and equalizer filter matrices. Applying these filters to the frequency-selective MIMO channel, converts it to some non­frequency-selective SISO channels. Therefore, both inter-channel and inter-symbol interferences are canceled. Simulation results show that the proposed method has a high performance. CP - IRAN IN - LG - eng PB - ITRC PG - 11 PT - Research YR - 2009
