An Enhanced Spectral Efficiency Chaos-Based Symbolic Dynamics Transceiver Design
Abstract
Chaotic synchronization performs poorly in noisy environments, with the main drawback being that the coherent receiver cannot be implemented in realistic communication channels. In this paper, we focus our study on a promising communication system based on chaotic symbolic dynamics. Such modulation shows a high synchronization quality, without the need for a complex chaotic synchronization mechanism. Our study mainly concerns an improvement of the bandwidth efficiency of the chaotic modulator. A new chaotic map is proposed to achieve this goal, and a receiver based on the maximum likelihood algorithm is designed to estimate the transmitted symbols. The performance of the proposed system is analyzed and discussed.
