Such work underscores the global significance of sub-Nyquist sampling and FRI signal processing, with implications for accelerating multidimensional spectroscopic techniques and broadening the ...

Sub-Nyquist sampling and Finite Rate of Innovation (FRI) signal processing represent a paradigm shift in the acquisition and reconstruction of signals. Traditional sampling theories require adherence ...

How to form a radio image Forming images of the sky in radio astronomy using interferometers is inherently a digital signal processing (DSP)-intensive task. Signals from all antennas are digitized, ...
