A Fine Spectrum Sensing Procedure based on Modulated Wideband Converter

2019 International Conference on Communication and Signal Processing (ICCSP), 2019
For the effective implementation of Cognitive Radio (CR) networks, it is important to perform wideband spectrum sensing rapidly and efficiently. Due to the wide frequency bands involved in spectrum sensing, sub-Nyquist sampling schemes have gained importance.

Analysis and Signal Recovery of Modulated Wideband Converter with Gain Mismatch

Applied Mechanics and Materials, 2013
Recently, a sub-Nyquist sampling system, called as Modulated Wideband Converter (MWC), for sparse analog signals is proposed in [1]. In this paper, the gain mismatch, i.e. the gain variation of the mixers, the low pass filters and the low-date rate ADCs, in the MWC is, firstly, analyzed.

Compressed sampling signal detection method based on modulated wideband converter

2016 IEEE Advanced Information Management, Communicates, Electronic and Automation Control Conference (IMCEC), 2016
In order to deal with the problem when the bandwidth of the passive radars and wideband digital receivers are getting bigger and bigger, causing that the traditional signal detection methods need a high sampling rate and a large number of sampling points.

A new approach to near-theoretical sampling rate for modulated wideband converter

2014 International Conference on Signal Processing and Communications (SPCOM), 2014
For a multiband signal, the minimum sampling rate required for an arbitrary sampling method, which allows perfect reconstruction, is NB, where N is the number of bands and B is the maximum bandwidth. It has been proposed in the literature that, if the carrier frequency information of a multiband signal is not known apriori, then we require a minimum ...

Online Calibration of Modulated Wideband Converter Online Calibration of Modulated Wideband Converter

In this work, we propose a new method for online calibration of recently proposed Modulated Wideband Converter (MWC), which digitizes wideband sparse signals below the Nyquist limit without loss of information by using compressive sensing techniques.
