Blind Channel Estimation Based on Optimal Window Function and HOS for MIMO System

Abstract

The multiple transmit and receive antennas can be used to improve communication quality and capacity. In this paper, a blind channel estimation method based on optimal window function and HOS for MIMO system in the frequency domain is proposed, simulation results show that the algorithm outperforms conventional algorithm with respect to the ONMSE by 2dB.In addition, the proposed method is utilized to identify minimum phase systems and non-minimum phase systems.
