主　　题：adaptive feedback cancellation affine projection global speech absence probability(GSAP) 

摘      要：A novel approach is proposed for improving adaptive feedback cancellation using a variable step-size affine projection algorithm(VSS-APA) based on global speech absence probability(GSAP).The variable step-size of the proposed VSS-APA is adjusted according to the GSAP of the current *** weight vector of the adaptive filter is updated by the probability of the speech *** performance measure of acoustic feedback cancellation is evaluated using normalized *** results demonstrate that the proposed approach has better performance than the normalized least mean square(NLMS) and the constant step-size affine projection algorithms.
