Abstract :
In this paper, we propose the channel-whitening blind sequence estimation (CW-BSE) algorithm followed by a least square estimator for blind channel estimation, and analyze the performance of the CW-BSE algorithm. Simulation shows that when signal-to-noise ratio is larger than 8 dB, the mean squared error of estimated channel parameters achieves the Cramer-Rao bound for estimators using training sequence
