Abstract:Analysis and processing of the non-stationary random signals is a research hot spot nowadays. In this paper, the analytical methods for the non-stationary random signals based on parameter models, such as adaptive AR spectral analysis, analysis of the non-stationary random signals as the stationary random signals, time-varying parameter model and parameter model based on non-parameter model analysis are studied, and the latest progress of this frontier is reviewed. At the end of the paper, some problems yet to be studied are addressed.
Keywords:AR model  Time-varying AR model  Time-varying ARMA model  Piecewise stationary AR model  Non-stationary random signal
