Blind Separation of Single-channel Chaotic Signals in the presence of Noise
The problem of blind separation of single-channel chaotic signals is considered in the presence of noise. When only one signal that is a combination of several unknown chaotic signals is acquired, the composite chaotic signals and unknown parameters are considered as a high dimension state. Based on the principle of Bayes theory, blind separation of chaotic signals is achieved by estimating the join posterior probability density of this state. Adaptive iteration algorithm is used to estimate the noise and the Kernel Smoothing method is adopted to iteratively estimate the fixed parameters. The simulation results show that the proposed method can solve the blind separation of the single-channel chaotic signals with noise effectively.
