Instantaneous Frequency Estimation of FM Signals Using the T - Class of Time-Frequency Distributions

چکیده

Recently we have proposed the T-class of time-frequency distributions (TFD’s) with time-only kernels to provide high-resolution and considerable cross-terms reduction for multicomponent FM signals. In this work we investigate the instantaneous frequency (IF) properties of two members of this class: the hyperbolic and the exponential T-distributions in the presence of noise. A comparison with two well-known TFD’s, Wigner-Ville and Choi-Williams distributions, is also considered.

Design of time-frequency distributions for amplitude and IF estimation of multicomponent signals

This paper p n a n t s a new class of time-frequency distributions (TFDs) suitable for efficient amplitude and instantaneous frequency (IF) estimation of monoand mud tiwmponent FM signals. The main characteristic of these TFDs, referred to as T-distributions, is that their kernels are functions of time only in the time-lag domain, hence the name time-only kernels. It is shown that separable tim...

Performance of quadratic time-frequency distributions as instantaneous frequency estimators

General performance analysis of the shift covariant class of quadratic timefrequency distributions (TFDs) as instantaneous frequency (IF) estimators, for an arbitrary frequency-modulated (FM) signal, is presented. Expressions for the estimation bias and variance are derived. This class of distributions behaves as an unbiased estimator in the case of monocomponent signals with a linear IF. Howev...

Estimating the number of components of a multicomponent nonstationary signal using the short-term time-frequency Rényi entropy

The time-frequency Rényi entropy provides a measure of complexity of a nonstationary multicomponent signal in the time-frequency plane. When the complexity of a signal corresponds to the number of its components, then this information is measured as the Rényi entropy of the time-frequency distribution (TFD) of the signal. This article presents a solution to the problem of detecting the number o...

The T-Class of Time - Frequency Distributions: Time-Only Kernels with Amplitude Estimation

This paper presents a class of time frequency distributions (TFDs) characterized by time-lag kernels which are functions of time only. If the parameters of the timeonly kernels are properly chosen, their corresponding TFDs, the T-distributions, are more efficient than their two-dimensional counterparts in terms of cross-terms suppression while keeping a high energy concentration (resolution) ar...

Time-frequency analysis of normal and abnormal biological signals

Due to the non-stationary, multicomponent nature of biomedical signals, the use of time-frequency analysis can be inevitable for these signals. The choice of the proper time-frequency distribution (TFD) that can reveal the exact multicomponent structure of biological signals is vital in many applications, including the diagnosis of medical abnormalities. In this paper, the instantaneous frequen...
