| Abstract: | The soft threshold for white noise reduction have been improved. And estimated the signal parameters based on the wavelet transform coefficients. Compare with others, this method can be more accurately estimate the important signal parameters just like the arrival time of pulse. Approved by the simulations,this method also satisfied the requariments of veracity and real time. |

| Keywords: | signal processing wavelet threshold low signal to noise ratio parameters estimate |
