Estimation of the instantaneous amplitude and frequency of non-stationary short-time signals
We consider the modeling of non-stationary discrete signals whose amplitude and frequency are assumed to be nonlinearly modulated over very short-time duration. We investigate the case where both instantaneous amplitude and frequency can be approximated by orthonormal polynomials. Previous works dealing with polynomial approximations refer to orthonormal bases built from a discretization of con...

15 صفحه اولTime-Frequency Domain Characterization of Stationary and Non stationary Signals
Abstract-This paper presents the various methods for the spectral analysis of signals for the stationary as well as non-stationary signals. Due to non-stationary characteristics of the signals, it has been always a challenge to achieve time frequency distribution of such signals. Between the various techniques of signal analysis, this paper uses Fourier transform, Short time Fourier transform, ...
متن کاملSome Remafws on Instantaneous Amplitude and Frequency of Signals
The most common way to define instantaneous amplitude, phase and frequency of a real signal is to use its analytic signal. One of the main advantages of this procedure is that it establishes a one-to-one relationship between any real signal and the pair of functions defining its instantaneous amplitude and phase. However, there are some problems in its physical interpretation but it is shown th...
متن کاملTime frequency and array processing of non-stationary signals
Introduction and overview Conventional time-frequency analysis methods were extended to data arrays in many applications, and there is the potential for more synergistic development of new advanced tools by exploiting the joint properties of timefrequency methods and array signal processing methods. Conventional array signal processing assumes stationary signals and mainly employs the covarianc...
