Abstract: One-unit ICA-R is an efficient method utilizing prior information to extract an expected source signal. A fixed-point algorithm for one-unit ICA-R is proposed when absolute value of kurtosis is considered as contrast function in this paper. The algorithm avoids the second derivative of contrast function and simpilifies operation accordingly. The fixed-point algorithm can converge faster than Newton fast algorithm based on kurtosis. At last, computer simulations verify the validity of the proposed algorithm.
