Chaotic signal has the property of synchronization; data are transmitted from one location to another by mapping bit sequences to symbols, and symbols to sample functions of analog waveforms. The synchronization between two digital chaotic oscillators, serving as a transmitter-receiver scheme. At the receiver, the symbol may be recovered by means of coherent detection, where all possible sample functions are known, The oscillators exhibit rich chaotic behavior and are unidirectional coupled, forming a master-slave topology. Chaotic signal generation where an oscillator based on linear system is used to generate random signals which are highly deterministic in nature. A chaotic circuit to generate chaotic signal, A/D converter, D/A converter and a digital processing mechanism to control all signal flows and perform I-CDPK modulation corresponding to input digital bits. The system output is sent to ICDM’s chaotic circuit through both transmitter and receiver.
