  • An accelerated acoustic echo cancellation algorithm is proposed in this paper based on Parallel Subgradient Projection (PSP) technique. Through the angle optimization strategy, accelerated method optimizes the input signal spaces belong to different states and finds a pair of optimal projection spaces. Then adaptive algorithm can be accelerated by projection onto the pair of optimal half spaces. Experiment indicates the accelerated method possesses more rapid convergence speed than traditional algorithm. Additional, system performance gets promoted no matter evaluated by mean square error or echo path misalignment.
