The autocorrelation matching method is a second order statistics-based blind MIMO FIR channel equalization technique designed for wireless communication systems using multiple receiving antennas. This paper presents a closed-form solution to the optimal zero-forcing equalizer for the autocorrelation matching method. It can recover a transmitted signal with maximum SNR from an unknown MIMO FIR channel based on the autocorrelation coefficients of the transmitted signal and the autocorrelation matrices of the received signals. Numerical results obtained from intensive computer simulations are also given in this paper, which verify the effectiveness and accuracy of the closed-form solution.
