| Abstract: | In order to heighten the precision of signal processing, a wavelet-based adaptive deconvolution filter is presented by hybridizing the least mean square filter, the Kalman filter and the wavelet transform. A lot of simulated experiments have been carried out by using the scheme. The results show that the filter can track the reflection coefficient signals and cancel the high frequency noises, and that the average relative error rate is within 1%. This indicates that the scheme is very efficient. |
