Chaos based Communication System Using Reed Solomon (RS) Coding for AWGN & Rayleigh Fading Channels

Chaotic signals are non-periodic, random-like and bounded signals that are generated in a deterministic manner using chaotic mapping techniques and exhibits sensitive dependence on initial conditions. Even though a small difference is introduced between the initial values, the two chaotic signals separate rapidly from each other after a short time period. Using these mapping techniques various techniques for modulation of chaos shift keying signals have been implemented and simulated. And synchronization of chaos is verified by using same mapping technique at both transmitter and receiver. The data information symbols are firstly coded by a Reed Solomon (RS) coder. RS are powerful error correcting codes that can be employed in a wide variety of digital communication systems. Interleaving is a technique commonly used in communication systems to overcome correlated channel noise such as burst errors or fading using RS coder the performance of the chaos systems are improved.
