Research on feature extraction of impulse signal using walsh transform 变换对冲击信号序列特征提取的研究
These experiments indicate that the prediction model built with traffic volume time series after noise reduction can yield better results 用小波变换对交通量数据进行消噪处理,即通过多分辨率的小波分解和重构来实现消噪。
Firstly , using wavelet decomposition theory , the system feature reference data series are decomposed into two parts : low frequency part and high frequency part 首先,应用小波变换对系统的特征参数序列进行分解,得到低频部分和高频部分。
Through the laplace transform method , the author has a systemic study on the tolerable differential settlement of the bridge approach with and without approach slabs 本文通过拉普拉斯变换对设和不设搭板路桥过渡段的容许差异沉降进行了系统研究。
Wavelets analysis is a promising approach to process ultra - wide band radar signal . it has tremendous potential to combine wavelets with ultra - wide band radar 由于小波变换对超宽带雷达信号的分析具有独特之处,将二者相结合的研究具有巨大的潜力。
