摘要
肌电信号的检测与分析对临床诊断以及康复医学具有重要意义。肌电信号的特点是强噪声背景下的生物信号,对肌电信号的检测和提取具有一定的难度。我们针对肌电信号的特点以及与噪声的关系,采用小波包变换的方法进行去噪研究。通过仿真以及在自主开发的便携肌电诱发电位测量系统中的应用,说明该方法对肌电信号的去噪是有效的。
The detection and analysis of electromyographic signal is of far reaching importance for clinical diagnosis as well as for convalescence medicine. Electromyographic signal is a kind of biological signal in the background full of noise, so it is somewhat difficult to detect and extract the electromyographic signal. In this paper is discussed how to use the method of wavelet package transform to denoise the electromyographic signal on the basis of its feature and its relationship with noise. The results of simulation and application in the Electromyographic Evoked Potential Measuring Systm independently developed by our laboratory illuminate that the method is effective for denoising electromyographic signal.
