چکیده

A strategy for filtering (or denoising) of high-pass signals embedded in an impulse (heavy tail) noise environments based on the robust DFT forms has been proposed recently. In this paper we investigate various approaches for design of the robust DFT used in this application. We consider the DFT estimates based on the: linear combination of order statistics (L-estimate), myriad, and Wilcoxon estimate. Possible adaptive strategies for selection of parameters in these robust estimation schemes are also investigated.

Removal of Α-stable Noise in Frequency Modulated Signals Using Robust Dft Forms

A task of filtering (denoising) of high-pass signals corrupted by heavy tail (α-stable) noise is considered. For this purpose, several techniques based on the robust DFT forms have been proposed recently. In this paper we study various approaches for design of the robust DFT and compare their performance for frequency-modulated (FM) signals. In particular, we consider the DFT estimates based on...

Robust Space/Spatial-Frequency based Filtering of Images in the presence of heavy tailed noise

A robust space/spatial-frequency representation for analysis of two-dimensional signals corrupted by heavy tailed noise is proposed. The L-estimate forms of robust short-time Fourier transform and spectrogram for 2D signals are introduced. They are used to define a non-stationary space-varying filtering procedure in the space/spatial-frequency domain. The efficiency of the proposed procedure is...

Robust 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...

An Overview of the Adaptive Robust DFT

This paper overviews basic principles and applications of the robust DFT (RDFT) approach, which is used for robust processing of frequency-modulated (FM) signals embedded in non-Gaussian heavy-tailed noise. In particular, we concentrate on the spectral analysis and filtering of signals corrupted by impulsive distortions using adaptive and nonadaptive robust estimators. Several adaptive estimato...

Robust DFT-based filtering of pulse-like FM signals corrupted by impulsive noise

Filtering of pulse-like FM signals with 1 varying amplitude corrupted by impulse noise is consid2 ered. The robust DFT calculated for overlapped inter3 vals is used for this aim. This technique is proposed in 4 order to decrease amplitude distortion of output signals 5 that can be introduced by the robust DFT calculated 6 within a wide interval including possible zero-output. 7 The proposed alg...
