Identification and equalization of MC-CDMA system driven by stochastic chaotic code
Résumé
In this contribution, we consider the problem of blind identification of Finite Impulse Response (FIR) system driven by a stochastic chaotic signal. Because of the inherently deterministic nature of a chaotic signal, we initialize the recursive equation which define the chaotic signal, by a random number, this leads to a random excitation. It was observed that the equalization performance of the chaotic approach was superior to the conventional statistical method. This is another benefit for using chaos in a spread spectrum communication system.
