摘要
研究了基于小波变换的信号检测方法及它在不同尺度上分析和处理信号的各种频率成份 .用非线性小波阈值的方法去除噪声 ,使有用信号能从噪声中检测出来 ,提高信号的分辨率、信噪比 .
In the paper are studied the way of the detection of signals based on wavelet transform and its analysis and processing of signals of various frequencies at different scales. The method of nonlinear wavelet threshold denoising can detect useful signals from the noise to improve the resolving power and signal to noise ratio of signals.
