摘要：This paper addresses the problem of blind signal extraction. A constrained optimization problem is introduced which takes into account the constraint about a desired source signal. After solving the optimization problem, a learning algorithm is presented based on the gradient maximize learning rule. One can extract the desired source signal while its coarse normalized kurtosis range is known in advance. Computer simulations on biomedical signals illustrate the efficiency of the proposed method. © 2014 ICIC International.
