AMPLITUDE-INDEPENDENT CHAOTIC SYNCHRONIZATION

There has recently been speculation on whether or not chaotic synchron ization might be useful for communications. One problem with using cha otic synchronization to communicate is that the response system is non linear, so that any variation in the amplitude of the chaotic driving signal degrades the synchronization of the response system to the driv e system. In the present work, I show that it is possible to design a response system that reproduces a scaled version of the chaotic drivin g signal when the drive signal is attenuated or amplified. A simple co mmunications system is demonstrated to show that the type of synchroni zation described here is useful, and the effects of noise on the commu nications system are studied.
