Abstract :
A method of synchronizing two chaotic systems by implementing an extended Kalman filter (EKF) as part of the receiver is presented. Communication is accomplished by parameter modulation in the transmitter and parameter estimation in the receiver filter and tolerates nontrivial parameter mismatches as well as additive noise. Several parameters may be modulated and estimated concurrently, resulting in simultaneous multiple access of a single channel
