摘要
A method for transmitting multiple digital information signals by a single transmitted chaotic signal is presented.The information signals are encoded by modifying some tunable parameters of a chaotic system and decoded at the receiver by following the parameter modulation in the transmitter via synchronization.The Lorenz system is used to demonstrate the validity,robastness and security of the method.
