Performance Analysis of Non-Coherent Chaotic On-Off Keying Systems

Abstract

Recently, many researches focus on chaotic signal systems because of non-periodic, random-like fashion and wide band essential. In chaotic system, there are several modulation schemes such as chaotic shift keying (CSK), differentially chaotic shift keying (DCSK) and chaotic on-off keying (COOK). COOK is more favorable than others since it is not necessary to know the initial condition of chaotic basis function and easy to implement.his paper, we derive the bit error rate (BER) of COOK on additive white Gaussian noise (AWGN) channel and compare it with simulation results.
