Abstract Wavelet filtering is a new research in the field of signal processing in the last decade. It has predominance over the traditional filtering methods. This paper presents the principle, model and characteristics of wavelet denoising method, basing on the analysis and synthesis of developments in this research domain in the past few years. Wavelet denoising methods are sorted into three groups and they are commented. This paper pays attention to the key points, existing problems and the thought of how to solve these problems.
