摘 要：In this chapter, we propose an adaptive equalization scheme for a chaos-based digital communication system. The studied system is a discrete-time version of the one proposed by Wu and Chua that has recently been considered for optical applications. Due to the nonlinear characteristics of the transmitters and receivers and the lack of robustness of chaos synchronization, even minor channel imperfections are enough to hinder communication. Adaptive equalization is succinctly reviewed by focusing on the normalized least-mean-squares (NLMS) algorithm, which is extended to fit the studied chaotic communication system. Simulation results show that the proposed chaotic NLMS can successfully equalize the channel.
