Abstract

In this paper, we proposed a noise reduction algorithm based on gradient descent method in order to reconstruct pseudo trajectories in the neighborhood of true chaotic signal, firstly. Then, a modulation-demodulation chaos shift keying (CSK) scheme for data transmission which assumes a priori knowledge of the dynamics of chaotic carriers at the transmitter is developed. The similarity between the reconstructed attractor and that representing the sent symbol at transmitter could be utilized to detect the sent symbol, effectively. We show that this detection method can achieve bit error rate performance comparable to that of other non-coherent chaos based communication systems.
