Wiener–kolmogorov Filtering, Frequency-selective Filtering and Polynomial Regression
The classical theory of statistical signal extraction presupposes lengthy data sequences, which are assumed, in theory, to be doubly infinite or semi-infinite— see Whittle (1983), for example. In many practical cases, and in most econometric applications, the available data are, to the contrary, both strongly trended and of a limited duration. This paper is concerned with the theory of finite-s...
متن کاملA Family of Selective Partial Update Affine Projection Adaptive Filtering Algorithms
In this paper we present a general formalism for the establishment of the family of selective partial update affine projection algorithms (SPU-APA). The SPU-APA, the SPU regularized APA (SPU-R-APA), the SPU partial rank algorithm (SPU-PRA), the SPU binormalized data reusing least mean squares (SPU-BNDR-LMS), and the SPU normalized LMS with orthogonal correction factors (SPU-NLMS-OCF) algorithms...
متن کاملRemoval of Impulse Noise by Selective Filtering
In this paper we present a novel structure for removal of impulse noise which is based on a combination of impulse detection and nonlinear ltering. The impulse detector is realized as a neural network which will be shown to possess a very simple structure. This means that, compared to traditional approaches, a signiicant gain in performance can be achieved with considerably smaller complexity. ...
متن کاملRobust Frequency - Selective Filtering usingWeighted Myriad Filters
Weighted Myriad Smoothers have recently been proposed as a class of nonlinear l-ters for robust non-Gaussian signal processing in impulsive noise environments. However , weighted myriad smoothers are severely limited, since their weights are restricted to be non-negative. This constraint makes them unusable in bandpass or highpass ltering applications which require negative lter weights. Furthe...
متن کاملAmplitude-selective filtering for remote-PPG.
Biometric signatures of remote photoplethysmography (rPPG), including the pulse-induced characteristic color absorptions and pulse frequency range, have been used to design robust algorithms for extracting the pulse-signal from a video. In this paper, we look into a new biometric signature, i.e., the relative pulsatile amplitude, and use it to design a very effective yet computationally low-cos...
