Performance Comparison of Different Equalization Techniques for 4 ×4, 3×3, 2×2, 2×3, and 2×4 MIMO wireless communication systems

MIMO technology can enhance the channel capacity as a result huge number of data can be transmitted within a short span of time. The number of more antennas in the transmitter and receiver section is a source of the number of more channel capacity in the wireless communication system. Multiple antennas are used by the MIMO system in the transmitter and receiver section. This paper represents the performance of the different equalizer techniques for 4×4, 3×3, 2×2, 2×3, and 2×4 MIMO wireless communication systems under the Rayleigh fading channel. The main aim of this paper is to find out the minimum BER by comparing equalizers techniques with four 4×4, 3×3, 2×2, 2×3, and 2×4 MIMO wireless communication systems. All the modulation process is done by BPSK. Four equalizers are considered here those are MLSE, MMSE, ZF and MF-SIC. Simulation is done by MATLAB software.
