A novel recursive scheme to compute the global and robust optimal variable fractional delay (VFD) filters based on the Particle Swarm Optimization (PSO) is developed in this paper. If the PSO is directly used to compute an optimal VFD filter the particles with high dimension might be yielded, which could require a long convergence time. Our recursive scheme invokes only the particles with much smaller dimension at each step of the computation. Experimental results demonstrate the effectiveness of the proposed approach.
