Abstract :
This paper proposes a simple and low complexity method for channel equalization of MIMO system. Channel equalization of multiple inputs multiple outputs cost 203 fading frequency-time selective channel is simulated. Temporal variations in channel are due to the Doppler spread, a sign of relative motion between transmitter and receiver. This paper applies the MIMO concept for gradient lattice filters which is low complexity in comparison with Kalman+DFE based equalization with compromising BER.
