摘要
小波分析法去噪是当前广泛应用的信号去噪方法,为研究小波分析去噪效果,本文首先对小波分析的基本理论进行介绍,然后介绍了小波去噪原理,最后通过MATLAB对小波去噪效果及影响因素进行实验仿真。仿真结果通过波形、信噪比SNR和最小均方误差MSE进行分析。
Wavelet analysis denoising is a widely used signal denoising method at present.In order to study the denoising effect of wavelet analysis,this paper first introduces the basic theory of wavelet analysis,then introduces the principle of wavelet denoising,and finally carries out experimental simulation on the effect and influencing factors of wavelet denoising through MATLAB.The simulation results were analyzed by waveform,SNR and MSE.
