摘要

Multiple antenna systems (Multiple Input, Multiple Output - MIMO) give a significant enhancement to data rate and channel capacity. In this paper work, we provide a comparative study & performance analysis of minimum mean square error, maximum ratio combining, & zero forcing equalization techniques. The simulation results are obtained using MATLAB. The simulation result shows that zero forcing equalizer based receiver is better than MMSE for noise free channel but MMSE is better than ZF for noisy channel. Different equalization approach called Minimum Mean Square Error (MMSE) equalization will be discussed. The channel as a flat fading Rayleigh multipath channel and the modulation as BPSK will be taken.
