Description
Since the 1970's, there has been a great deal of research effort spent on studying
chaotic systems and the properties of the chaotic
signals generated. Characterized by their wideband, impulse-like autocorrelation and low cross-correlation properties, chaotic signals
are useful spread-spectrum signals for carrying digital information. Spectrum spreading has become one of the most popular modulation
techniques for high-speed wireless communications. It makes use of signals of very wide bandwidth to carry information at relatively
low data rates, and possesses advantages such as low probability of interception, resistance to jamming, multiple-access capability and
mitigation to multipath effect, which are particularly important in a wireless scenario. In addition to enjoying the aforementioned benefits,
chaotic signals can be generated using simple circuitries, thus lowering the cost of transceivers.
Early study of chaos-based communication
systems was focused on a single-user case. In the past few years, more effort has been put on investigating systems with multiple-access
capability, which is a key feature of spread-spectrum communication systems. This book presents a detailed study of some multiple-access
schemes used for chaos-based communications, and evaluates their performance. In addition, the effectiveness of the multiuser detection
techniques, whose primary objective is to reduce interference between users and hence improve performance, is evaluated in the context
of multiple-access digital communication systems.
Audience
For graduate students and researchers who are involved in the study of chaos communications, also providing useful information for communication engineers and technology developers
