Self-Synchronizing Ergodic Maps and Chaotic Modulation

Abstract
Self-synchronizing chaotic systems can be used as synchronous pseudo-random sequence generators, though physical applications have been limited by the sensitivity of the synchronous state to noise. Using two separate time scales in conjunction with a digital filter supresses the noise in the coupling signal. We find this gives stable synchronous motion even for signal-to-noise ratios less than 1. As an application of these pseudo-random sequence generators we propose a chaotic modulation scheme based on ergodic maps. We characterize the performance of this system by bounding the mean synchronization time and estimating the resulting bit energy.Citation
