    摘要:

    非平稳性度量是非平稳信号处理中的重要课题。尽管已有的度量方法在原理上有较大差异,缺少统一的理论框架和度量标准,但这些非平稳信号度量方法都在其相应领域发挥了重要作用。本文对随机信号非平稳度量方法进行了综述,系统地总结、归纳了不同领域现有的随机信号非平稳性度量方法,包括基于统计量和动力学参数的时域方法、时频域参数方法、信号建模参数方法以及特定类别信号的非平稳性度量方法,给出了各种度量方法的应用,并展望了非平稳性度量的未来发展方向。

    Abstract:

    Measuring non-stationary level is an important topic in non-stationary signal processing. Although the existing measurement parameters and methods have obvious differences in principle and are not derived from a unified theoretical framework and metrics, these measurements play an important role in the corresponding fields. This paper summarizes the measurement parameters and methods for the non-stationary signals in different research fields systematically, including the statistic and dynamic parameters in time domain, the parameters in time-frequency domain, signal modeling parameters and specific non-stationary signal measurements. Moreover, the applications of various measurement parameters and methods are given briefly. Finally, the future work on the non-stationary signal measurements is also deduced.
