ICI CANCELLATION IN MIMO-OFDM SYSTEM BY FREQUENCY BLIND EQUALIZER AND REPETATION TECHNIQUE

Abstract

This paper proposes a solution to reduce Inter-Carrier Interference in the MIMO-OFDM system. The solution is built from combination of frequency blind equalizer and sequence repetition. The blind equalizer is objective to maximize the independent metrics between subcarires by Independent Component Analysis Technique. The solution does not use trial signals in order to reduce interference. So, the transmission capacity is reduced. The simulation results show that this solution is more effective for slow fading transmission environment.
