| Abstract: | This article introduces TD-BP network which can simulate sealed noise channel filter to cancel noise better.Its model,learning algorithm and universal approximation are discussed.Noise canceller based on TD-BP network has the ability to parallel-distributed in signal processing.During cancellation,TD-BP network is used to approximate noise,then the noise is cancelled and the useful signal is recovered.The simulation result indicates that TD-BP network is robust and easy to use. |
