Chaotic communication using generalized synchronization

We present a new technique for the chaotic communication of a signal using the concept of generalized synchronization. We develop a general approach f or implementing our technique and illustrate it using a Rossler system driv ing a Lorenz system. It is demonstrated that the scheme is robust with resp ect to noise in the communication channel and to small parameter mismatches in the system. Finally, we discuss the advantages of this technique over e xisting methods and examine ways of improving the scheme. (C) 2000 Elsevier Science Ltd. All rights reserved.
