| Abstract: | This paper introduces both the method of the spectrum coding transmission of digital signal and that of wavelet threshold de noising in detail,and also studies the performance of the method of wavelet threshold de noising used in the bipolar linear phase coding.To find the best scheme of wavelet de noising,various parameters that influence the performance of wavelet de noising are studied in this paper.In the end,the statistics of the operational volume of wavelet de noising is made.The result indicates that the wavelet transform has practical value in the performance of de noising and real time processing. |
