摘要
基于小波变换的特点,分析了小波变换用于去噪的原理和方法,重点探讨了小波阈值去噪的原理和方法,并对小波分析和小波变换去噪在某些具体领域的应用情况作了简单介绍。
This paper introduces the characteristics of the wavelet transformation, and analyzes the principle and methods applied in wavelet transformation, which focuses on the principle and methods of wavelet shrinkage de-noising. It also discusses some specific applications of the wavelet de-noising, such as OFDM low voltage power line communication, image de-noising, and ultrasonic signal denoising etc.
