Abstract
Along with the increasingly quick development of modern communication system technologies, secure communication has become increasingly important. We propose a new method for secure communication systems. Independent component analysis (ICA) is employed to retrieve the message signal encrypted by a mixture of Gaussian white noise and chaotic noise. Unlike the traditional chaotic synchronization method, this method does not require knowing the basic Gaussian white noise and chaotic noise variables. However, the signals separated by traditional ICA shows opposite phase and unequal amplitude. Our study proposed a modified ICA, which can calculate accurately the phase and amplitude. The results showed that modified ICA could effectively extract the original message signal.
