以B-样条小波为分析小波,提出了用于分析化学重叠信号解析的新方法—连续样条小波变换。详细讨论了采用二阶、三阶、四阶基数B-样条小波函数时,连续样条小波变换对重叠信号的解析,结果表明:连续样条小波变换应用于分析化学信号的处理,能使峰变窄同时还能提高信号的信噪比,是一种新型有效的重叠信号解析方法;对比三种样条小波基的处理结果,二阶B-样条小波基优于其余两种。
Taking B-spline wavelet as analysis wavelet, a new method for analyzing chemical overlap signal is proposed, ie continuous spline wavelet transform. In this paper, we discuss in detail the analysis of overlapped signals by using continuous spline wavelet transform when using second, third and fourth radix B-spline wavelet functions. The results show that continuous spline wavelet transform can be used to analyze chemical signals, Narrowing the peak and increasing the signal-to-noise ratio of the signal at the same time is a new and effective method of overlapping signal analysis. Compared with the processing results of the three spline wavelet bases, the second-order B-spline wavelet base is superior to the other two.
