In this paper, a new method for blind interference cancellation of Multiple Input Multiple Output (MIMO) wireless communication systems based on Independent Component Analysis (ICA) is proposed. A proposed ICA algorithm exploits the Higher Order Statistical (HOS) of the observation signals for blindly interference cancellation and signals estimation processes is presented. In contrast to other methods, the proposed method does not require any modification in transmission side or using the training sequences that usually costs a bandwidth. Simulation results show the ability of the proposed algorithm to cancel the interference effects of the multipath fading channel comparing with other ICA algorithms and conventional method.
