基于小波变换的ECG信号去噪系统设计,在信号采集时,身体的任一微小运动都会产生“基线漂移”,这是一种低频干扰,同时,由于肌电的存在又产生了高频的肌电噪声,由于空间电磁场的存在又使心电信号中混有50Hz的工频干扰。这些噪声不去除,就会影响下一步的信号处理。
综合运用数字信号处理的理论知识进行生物医学信号增强系统设计,实现ECG信号的去噪,从而加深对小波变换及其应用的理解,建立概念多分辨分析的概念,加深理解信号增强的原理、方法和步骤。本设计的主要内容是设计一个基于小波变换的ECG信号去噪系统,实现ECG信号的去噪。
(ECG signal denoising based on wavelet transform system design, signal acquisition, any small movement of the body will have a " baseline drift" , which is a low-frequency interference, while the high frequency due to the existence of the EMG muscle electrical noise due to the presence of electromagnetic field and the ECG signal mixed with a 50Hz power frequency interference. The noise is not removed, it will affect the next step in the signal processing. Use the theoretical knowledge of digital signal processing for biomedical signal enhancement system design to achieve the de-noising of ECG signal, so as to deepen understanding of the wavelet transform and its applications, to establish the concept of multi-resolution analysis of the concept, deepen the understanding of signal enhancement of the principle, the method and steps. The main elements of this design is the design of an ECG signal denoising based on wavelet transform denoising the ECG signals.)

图象增强小波变换将一幅图象分解为大小、位置与方向都不同的分量。在做逆变换之前能改变小波变换域中某些系数的大小,,这样就能够洋选择的放大所感兴趣的分量而减小不需要的分量。给定一个图象信号,用二维小波分析析对图象进行增强处理。
