Chi and Mendel [I], [9] analyzed the performance of the minimum-variance deconvolution (MVD). In this correspondence, a further analysis of the performance of the MVD filter is presented. We show that the MVD filter performs like an inverse filter and a whitening filter as SNR + 00, and like a matched filter as SNR + 0. The estimation error e (k) of the MVD filter is colored noise, but it becom...

in this article, the effect of cells' radius on the behavior of wavelength switching optical filter andthe effect of the radius of the optical filters' key characteristics such as wavelength resonance onan optical filter based on photonic crystals, have been investigated. currently, the most commonapplied mechanism for designing optical filter based on photonic crystals is using twome...

Criteria are obtained for a filter F of subsets of a set I to be an intersection of finitely many ultrafilters, respectively, finitely many κ-complete ultrafilters for a given uncountable cardinal κ. From these, general results are deduced concerning homomorphisms on infinite direct product groups, which yield quick proofs of some results in the literature: the Loś-Eda theorem (characterizing h...

Abstract In 1974, Erdős posed the following problem. Given an oriented graph H , determine or estimate maximum possible number of -free orientations n -vertex graph. When is a tournament, answer was determined precisely for sufficiently large by Alon and Yuster. general, when underlying undirected contains cycle, one can obtain accurate bounds combining observation Kozma Moran with celebrated r...

a fundamental aspect of signal processing is filtering. Filtering involves the manipulation of the spectrum of a signal by passing or blocking certain portions of the spectrum, depending on the frequency of those portions. In this paper, Digital filters are designed using frequency specifications. Matlab provides different options for digital filter design, which includes function, calls to fil...

We consider the localization problem for a unicycle robot equipped with range finders and moving in environments with nonsmooth geometry, i.e., whose obstacle-free region has a piecewise-linear boundary. Using the Multi-Hypothesis Density Filter, a novel multi-modal estimator based on the bayesian framework, an innovative localization system is devised and implemented on the ATRV-Jr robot. Expe...

We demonstrate an integrated programmable photonic filter structure capable of producing bandpass filters with both tunable passband bandwidth and center frequency. Such filters could provide dynamic pre-filtering of very wide bandwidth analogmicrowave signals, essential to the next generation RF-front ends. The photonic filter is constructed from an array of uncoupled identical filter stages, ...
