Chaotic Signals in Digital Communications

Preface

Chaotic signals are characterized by an aperiodic and limited behavior, which is generated by deterministic dynamical systems presenting sensitive dependence on initial conditions. Applications involving chaotic signals have been investigated in several areas, including signal processing and telecommunications.

Due to their properties, chaotic signals usually occupy a wide bandwidth and have an impulse-like autocorrelation function. Furthermore, the cross-correlation between signals generated from different initial conditions tends to be small. These features support the use of chaotic signals in spread spectrum techniques.

Since the beginning of the 1990s decade, many papers and books describing interesting and promising chaos-based ...
