Title: Blind Channel Equalization for Chaos-Based Communication Systems
Abstract: Side-effects of communication channel seriously impair practical performance of chaos-based communication systems. This paper addresses the issues of blind equalization for chaos-based communication systems. The starting point of this paper is to make use of the Unscented Transform (UT) and the modeling technique for signal, and a blind equalization algorithm is then proposed. It indicates by computer simulation that this algorithm can effectively reduce various distortions and noise in channel. In comparison with the EKF-based algorithm, UT-based algorithm has faster convergence speed and better equalization performance, when channel is with low signal to noise ratio (SNR).
