An Improved Approach for Blind Channel Estimation Based on Statistical Property Transform
Zhao Le-jun · Jisuanji fangzhen · 2008
Stacked system model of SIMO channel is introduced by considering channel output over sampling.The concept of statistical property transform is discussed according to the situation in which channel input is stationary with a priori known autocorrelation function.In this paper,closed-form solution of equivalent transformation matrix is concluded and an algorithm for blind identification suitable to stationary source is proposed.Through simulations,the algorithm's performance of estimation error and convergence is analyzed.Simulation results demonstrate that the proposed approach can equalize the channel driven by non-identically independent distribution input effectively.This algorithm also has advantages of high accuracy and fast convergence.
