Bibliography

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 ...
