Sub-Nyquist Sampling: Bridging Theory and Practice
Moshe Mishali, Yonina C. Eldar
Sampling theory encompasses all aspects related to the conversion of continuous-time signals to discrete streams of numbers. The famous Shannon-Nyquist theorem has become a landmar…
Xampling: Compressed Sensing of Analog Signals
Moshe Mishali, Yonina C. Eldar
Xampling generalizes compressed sensing (CS) to reduced-rate sampling of analog signals. A unified framework is introduced for low rate sampling and processing of signals lying in…
Wideband Spectrum Sensing at Sub-Nyquist Rates
Moshe Mishali, Yonina C. Eldar
We present a mixed analog-digital spectrum sensing method that is especially suited to the typical wideband setting of cognitive radio (CR). The advantages of our system with respe…
Xampling: Analog to Digital at Sub-Nyquist Rates
Moshe Mishali, Yonina C. Eldar, Oleg Dounaevsky +1
We present a sub-Nyquist analog-to-digital converter of wideband inputs. Our circuit realizes the recently proposed modulated wideband converter, which is a flexible platform for s…
Xampling: Signal Acquisition and Processing in Union of Subspaces
Moshe Mishali, Yonina C. Eldar, Asaf Elron
We introduce Xampling, a unified framework for signal acquisition and processing of signals in a union of subspaces. The main functions of this framework are two. Analog compressio…
Expected RIP: Conditioning of The Modulated Wideband Converter
Moshe Mishali, Yonina C. Eldar
The sensing matrix of a compressive system impacts the stability of the associated sparse recovery problem. In this paper, we study the sensing matrix of the modulated wideband con…
