Abstract

We propose an enhanced version of the DCSK (differential chaos shift keying) scheme where the chaotic carrier is exploited for conveying useful information. This is achieved by means of a pseudo-chaotic encoder which spreads the input sequence, approximating the dynamics of the Bernoulli shift. The information encoded in the chaotic carrier is retrieved by means of standard maximum-likelihood detection methods
