| Modeling of nonstationary stochastic time series has found wide applications in speech processing, biomedical signal processing, seismology and failure detection. In this paper, the problem of deening a time-dependent spectrum for a general class of nonstationary processes is addressed. A class of piecewise locally stationary processes is introduced. It… (More)
