Realization of Speech Enhancement Adaptive Algorithm Based on Improved Minimum Description Length Criterion

摘要：

A improved algorithm for the speech signal denoising based on minimum description length (MDL) criterion is proposed.The second of MDL criteria change into retained energy ratio in order to improve denoisin ability.The method of determining improved MDL function parameters is given,and selection of wavelet decomposition level and wavelet basis function are discussed.Simulation results show its denoising effect is better than wavelet soft-threshold algorithm and MDL criteria algorithm.
