| Abstract: | In order to restrain the traditional adaptive filter based on neural network from trapping in local optimum,and an adaptive filter based on three-tier neural network was designed. Improving PSO algorithm was used to optimize the mutation operator according to standard derivation of swarm fit value to inhibit local optimum.An adaptive noise canceller was designed with an adaptive filter.The simulation shows that this system has better noise cancellation capability compared to the traditional adaptive noise c... |
