Abstract :
Based on the traditional wavelet threshold denoising algorithm, a new threshold function is put forward, overcoming the discontinuous function of the hard threshold and solving the problem of the permanent bias in soft-threshold function. Simulation result indicates that the new threshold function is more effective and predominant than traditional wavelet threshold functions in M-PSK signal wavelet-domain denoising process.
