    Abstract :

    MIMO-OFDM proves to be an excellent transmission technique in wireless environments.This combination proves to be very beneficial, as MIMO means more number of antennas which would offer larger bandwidths and OFDM means effective utilization of resources.MIMO-OFDM technique has increased spectral efficiency.It provides extensive bandwidth to wireless LANs networks.The problem of ISI(Inter Symbol Interference ) occurs in MIMO-OFDM systems due to high data rates.ISI occurs because of Doppler’s Shift Effect.The transmission over such systems suffers from ISI,Multipath Fading etc.The presence of noise and ISI causes bit errors at receiver end.Hence Equalization becomes necessary to equalize these errors at receiver end.The Proposed Equalizer simulation will be performed on MATLAB to check BER at different values of SNR making it user friendly and it will result in minimized BER at improved SNR.
