Abstract

A novel chaotic spread spectrum acoustic communication method is proposed in this paper. A chaotic signal, generated by a hybrid dynamical system, is used as spread spectrum sequence and the corresponding chaotic matched filter is used to decrease the effect of multiple propagation and noises. The proposed method does not need the complicated channel modulation-demodulation and equalization technologies, which are necessary for conventional acoustic communication. Simulation results show the proposed method has lower BER as compared to some existing methods.
