Abstract

This paper presents a novel chaotic coding scheme for correlated band-limited source signals. Two low implementation non-linear difference equations are introduced that exhibit chaotic properties within the confines of a specific modulating range. The two chaotic maps demonstrate the spectral conditioning effects of the modulation regime and highlight the robust noise-whitening properties over limited perturbation ranges. The performance of the novel strategy is then evaluated for noise-free circuits and existing echo cancellation technology shown to be optimized.
