Implementation of Chaotic on Off Keying (COOK) Using a High Resolution Digital Chaotic Signal

This paper reports on the use of a twisted map digital chaotic sequence as a carrier signal in a COOK system. The sequence generated shows low cross-correlation properties with very large signal space which is desirable for spread spectrum communication. A potentially cost-effective solution for wideband communications is to use a wideband chaotic carrier. COOK offers the simplest solution to chaotic communication. In COOK, the chaotic signal is multiplied directly by the bit sequence to be transmitted, i.e. radiation of a chaotic signal is disabled for bit’0’ and enabled for bit ‘1. COOK offers the simplest solution to chaotic communication. Since non-coherent demodulation is used in COOK, synchronization is unnecessary. The system was simulated by SimulinkMatlab
