摘要: 本发明公开一种基于RLS自适应滤波器的胃电慢波信号检测方法,包括以下步骤:a.信号采集;b.信号放大;c.模拟信号转换成数字信号;d.信号处理;e.数据预处理;f.噪声估计;g.基于RLS自适应滤波器处理;本发明具有以下有益效果及优点:1.面向胃电慢波信号的自适应处理滤波器设计,即把心电、呼吸信号、抖动,以及信号放大装置本身的噪声的都作为胃电慢波信号的噪声,而对其进行自适应滤波器的设计,以降低滤波器的复杂程度。2.测量信号通过自适应滤波后的信号复现,即可以完成对胃电慢波信号的精确复现。
英文摘要: The invention discloses a method for detecting gastric electrogram slow wave signals on the basis of a recursive least squares (RLS) adaptive filter. The method comprises the following steps of: a, acquiring signals b, amplifying the signals c, converting analog signals into digital signals d, processing the signals e, preprocessing data f, estimating noises and g, processing on the basis of the RLS adaptive filter. The method has the following beneficial effects and advantages: 1, an adaptive processing filter for the gastric electrogram slow wave signals is designed by taking all noises of electrocardiograms, respiration signals, dithering and a signal amplification device as the noises of the gastric electrogram slow wave signals so as to reduce the complexity of the filter and 2, the signal reproduction after the signals pass through the adaptive filter is measured so that the accurate reproduction of the gastric electrogram slow wave signals can be finished.
