摘  要:
The preprocessing method for multiwavelets coefficients and filter of multiwavelets is presented and analyzed in the paper, and a denoising algorithm of the noisy speech signal is given on the basis of the CL. Experiments show that the method removes noise efficiently and holds audition effect better.
