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 time and 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 noise and present its correction method.

We have introduced a redundancy of the transferred data. At the transmitter, a bit is represented by five duplicated bits. At the receiver, the bit is read as the value that is duplicated more than two times.
