FIR Filtering of Discontinuous Signals: A Random-Stratified Sampling Approach

ICASSP 2020accepted

This paper presents a novel approach, based on random stratified sampling (StSa) technique, to estimate the output of a finite impulse response (FIR) filter when the input signal is either a piecewise-continuous function having first-derivative discontinuities (FDDs), or a piecewise-discontinuous fu…

A novel sub-Nyquist Fourier transform estimator based on alias-free hybrid stratified sampling

Bashar I. Ahmad, Andrzej Tarczynski

ICASSP 2016accepted

This paper introduces a novel method of estimating the Fourier transform of deterministic continuous-time signals from a finite number N of their nonuniformly spaced measurements. These samples, located at a mixture of deterministic and random time instants, are collected at sub-Nyquist rates since…
