Abstract :
We propose a chaos-based multiplex communication system. The transmitter consists of N pieces of chaotic pulse-train generators (CPGs) and an adder. We confirm that unstable periodic pulse-train from the CPG can be stabilized by applying a certain sawtooth wave to the CPG. Then the transmission signal is made by summing the stabilized unstable pulse-trains. In the receiver side, the demultiplex function is realized by using some sub-circuits of the CPGs and a dynamic winner-take-all circuit. The demultiplex dynamics is guaranteed by both theory and experiments
