Abstract

We propose a new communication scheme that uses time-delayed chaotic systems with delay time modulation. In this method, the transmitter encodes a message as an additional modulation of the delay timeand then the receiver decodes the message by tracking the delay time.We demonstrate our communication scheme in a system of coupled logistic maps.Also we discuss the error of the transferred message due to an external noiseand present its correction method.
