Abstract: -Multi-input multi-output orthogonal frequency division multiplexing (MIMO-OFDM) has become a promising candidate for next generation broadband wireless communications.we theoretically analyze the performance of IAR with optimum equalization, and also provide highly accurate channel estimation of the OFDM. Simulation results show that the proposed receivers effectively recover contaminated OFDM signals with a moderate computational complexity.
