摘要
该文提出了一种方差平稳随机信号的处理方法——信号分解法。通过信号分解法对待处理信号进行分解,可得到方差平稳随机信号的趋向性序列,其余部分便是方差平稳随机信号中剔除趋向性后的零均值的平稳随机信号,它可用平稳随机信号模型来研究。该方法简单、通用,是处理方差平稳随机信号的一般方法。该方法得到的趋向性序列能更准确地逼近非平稳随机信号的趋向性曲线。
A. method for analyzing variance-stationary random signal is presented. It is designated as signal decomposition method. With the presented method, the trend component series can be obtained from the variance-stationary random signal; the rest of it is zero-mean stationary random signal that can be studied with the parametric model of stationary random signal. This method, simple and commonly used, is the general method to process the signal. The trend component series derived from this way can near more exactly the trend component curve of the variance-stationary random signal.
