摘要：
We discuss an approach of chaotic signal communication that is based on the synchronization of two identical nonlinear systems. Along with the procedure of decoding a pair of unknown chaotic signals, a parameter of the transmitting system is estimated through adaptive evolution. The signals are actually two dynamical variables of a nonlinear system. As one of the parameters of the transmitting chaotic system is unknown, security is assured against external interceptions. A periodic signal is also transmitted and it is recovered directly without any parameter estimation. (C) 2004 Elsevier B.V. All rights reserved.
