A novel online algorithm is proposed for blind source separation based on the conjugate gradient method. The probability density function is first estimated using a Gram-Charlier expansion, and then the score function is calculated to form the algorithm. The conjugate gradient method is then used in the novel algorithm, and the line search method is applied to find the best learning rate. Simulation and comparison show the algorithm's ability to perform the separation even with an ill… CONTINUE READING
