Abstract

Abstract: Papers of lifting wavelet transform on the coal bunker radar level meter signal noise reduction research, analyzes the various wavelet to threshold selection method.This paper proposes a new noise reduction method of threshold value, and the proposed method has carried on the simulation.The results show that the new method can effectively improve the SNR of signal, reduce the root mean square error signal.

Key words: Lifting wavelet transform, threshold, denoising, MATLAB
