Broadband Cooperative Spectrum Sensing Based on Distributed Modulated Wideband Converter [PDF]

open access: yesSensors, 2016
The modulated wideband converter (MWC) is a kind of sub-Nyquist sampling system which is developed from compressed sensing theory. It accomplishes highly accurate broadband sparse signal recovery by multichannel sub-Nyquist sampling sequences.

Sparse-Bayesian-Learning-Based Wideband Spectrum Sensing With Simplified Modulated Wideband Converter

open access: yesIEEE Access, 2018
Wideband spectrum sensing is an important aspect of cognitive radio systems. In current models of wide spectrum sensing, a discrete frequency denotes a continuous frequency band. This type of model is divorced from practice and cannot reflect the reality

Expected RIP: Conditioning of The modulated wideband converter [PDF]

open access: yes2009 IEEE Information Theory Workshop, 2009
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 converter, a recently proposed system for sub-Nyquist sampling of analog sparse signals.

Sub-Nyquist processing with the modulated wideband converter [PDF]

open access: yes2010 IEEE International Conference on Acoustics, Speech and Signal Processing, 2010
Sub-Nyquist systems capture the signal information in a different fashion than uniform high-rate samples. Consequently, digital processing, which is the prime reason for leaving the analog domain, becomes challenging. We propose a digital algorithm that translates samples obtained by the modulated wideband converter, a recent sub-Nyquist system, to the
