Abstract:

In this paper de-noising techniques are investigated in connection with secure wideband chaotic communication systems. An alternate version of the recently proposed Ueda chaotic communication system based on the initial condition modulation (ICM) of the chaotic carrier by the binary message to be transmitted is proposed and evaluated in the presence of noise, demonstrating a significant improvement. It is then shown that the running average finite impulse response (FIR) filter, and the hard-threshold filtering techniques in Haar and Daubechies wavelet domain can be used to significantly improve the performance of the proposed chaotic communication system.
