Low-Bit Quantization Methods for Modulated Wideband Converter Compressed Sensing [PDF]
2019 IEEE Global Communications Conference (GLOBECOM), 2019 This paper studies the impacts of low-bit quantization to wideband signal reconstruction with a sub-Nyquist sampling scheme Modulated Wideband Converter (MWC). Several real types of analog-to-digital converters (ADCs) are firstly simulated to the MWC and their results on wideband signal reconstruction are compared based on the low- bit criterion of the

Spectrum Sensing Using Co-Prime Array Based Modulated Wideband Converter [PDF]
Sensors, 2017 As known to us all, it is challenging to monitor wideband signals in frequency domain due to the restriction of hardware. Several practical sampling schemes, such as multicoset sampling and the modulated wideband converter (MWC), have been proposed. In this work, a co-prime array (CA) based modulated wideband converter (MWC) spectrum sensing method is ...

Expected RIP: Conditioning of The modulated wideband converter [PDF]
2009 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.

Structured dictionary optimization: application to the modulated wideband converter
2019 IEEE 8th International Workshop on Computational Advances in Multi-Sensor Adaptive Processing (CAMSAP), 2019 We consider the Modulated Wideband Converter (MWC) architecture [3] that aims at sub-Nyquist reconstruction of sparse wideband signals. The goal of this paper is to optimize the selection of the periodic sequences which are used to alias the spectrum of the input signal.

Sub-Nyquist processing with the modulated wideband converter [PDF]
2010 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

Wideband spectrum sensing based on advanced sub-Nyquist sampling structure
EURASIP Journal on Advances in Signal Processing, 2022 As the bandwidth increases, the high-speed sampling rate becomes the bottleneck for the development of wideband spectrum sensing. Wideband spectrum sensing with sub-Nyquist sampling attracts more attention and modulated wideband converter (MWC) is an ...
