Research of speech signal denoising based on Wiener adaptive filtering algorithm

This paper studies speech signal denoising based on the Wiener adaptive filtering LMS algorithm and RLS algorithm.Voice signal and noise in the relevant and irrelevant,smooth and not smooth the four cases,denoising speech signal analysis is discussed.respectively RLS and LMS algorithm.The study found regardless of the signal and noise in any one of the above four cases,RLS algorithm is superior,and in dealing with the greater advantage of the associated and non-stationary case.Irrelevant and stationary case,the LMS algorithm is better.
