Instantaneous Frequency Estimation Using The Wigner Distribution With Varying And Data-driven Window - Signal Processing, IEEE Transactions on
Estimation of the instantaneous frequency (IF) of a harmonic complex-valued signal with an additive noise using the Wigner distribution is considered. If the IF is a nonlinear function of time, the bias of the estimate depends on the window length. The optimal choice of the window length, based on the asymptotic formulae for the variance and bias, can be used in order to resolve the bias-varian...
متن کاملRobust Wigner distribution with application to the instantaneous frequency estimation
The Wigner distribution (WD) produces highly concentrated time–frequency (TF) representation of nonstationary signals. It may be used as an efficient signal analysis tool, including the cases of frequency modulated signals corrupted with the Gaussian noise. In some applications, a significant amount of impulse noise is present. Then, the WD fails to produce satisfactory results. The robust peri...
متن کاملPeriodogram with varying and data-driven window length
The short-time Fourier transform and the corresponding periodogram give biased estimates of the instantaneous frequency (IF) if the IF in question is a nonlinear function of time. In the case of noisy signals, the optimal choice of the window length, based on asymptotic formulae for the variance and bias, can resolve the bias—variance trade-off usual for nonparametric estimation. However, the p...
متن کاملInstantaneous frequency estimation by using the Wigner distribution and linear interpolation
Nonparametric algorithm for the instantaneous frequency (IF) estimation, by using the Wigner distribution (WD) with an adaptive window length, is considered in the paper. This algorithm produces a bias-to-variance trade-o7 close to optimal, meaning almost minimal mean squared error (MSE) of the estimation. Thus, the adaptive window length is characterized by a small bias at the considered insta...
متن کاملThe Wigner distribution of noisy signals with adaptive time-frequency varying window
Time–frequency representations using the Wigner distribution (WD) may be significantly obscured by the noise in observations. The analysis performed for the WD of discrete-time noisy signals shows that this time–frequency representation can be optimized by the appropriate choice of the window length. However, the practical value of this analysis is not significant because the optimization requi...
