Chaos shift keying: modulation and demodulation of a chaotic carrier using self-synchronizing Chua´s circuits

Describes a technique for transmitting digital information using a chaotic carrier. Each symbol to be transmitted is coded as an attractor in Chua´s circuit. The symbols are detected at the receiver by cascaded self-synchronizing Chua´s circuit subsystems. A proof of the synchronization effect is demonstrated using weak assumptions on the statistical behavior of the chaotic carrier to be transmitted. Furthermore a bound for the average time of synchronization is given. Results of both practical experimentation and simulations are presented which verify the approach
