In this paper, various channel estimation, interpolation and equalization techniques used in the analysis of MIMO configurations or formats are compared and the technique with the optimum performance determined. The channel estimation of these configurations were determined by modelling and simulating them in a wireless environment using MATLAB software. The figure of Merits used are the BER and MSE as a function of the SNR. The study revealed that MIMO is a more energy efficient technique since it achieved a good BER performance at lower transmit SNR, when compared to the MISO and SISO which requires higher SNR to achieve at same BER performance. This is as a result of the diversity and multiplexing gain experienced in the multiple antenna techniques using the STBC
