摘要: 简介小波概念之后,对一组模拟信号进行分析,采用小波变换,选出合适的小波函数,处理后再重构。对采用Mexican hat小波、Shannon小波、Meyer小波这三种不同小波得到的去噪结果进行比较,验证信号的滤波效果与选取的小波类型有较大的关系。

关键词: 信号分析, 小波变换, 去噪分析

Abstract: After the introduction of wavelet concept, using wavelet transform, the paper analyzes a group of simulation signals, chooses suitable wavelet function, then processes and reconstructs wavelet. Comparing three kinds of signal denoised by Mexican hat wavelet, Shannon wavelet and Meyer wavelet, the paper verifies the existence of a big concern between the effect of filter and selection of wavelet type.

Key words: signal analysis, wavelet transform, denoising analysis
