A ULA-Based MWC Discrete Compressed Sampling Structure for Carrier Frequency and AOA Estimation
IEEE Access, 2017 In this paper, we propose a new wideband digital receiver based on the modulated wideband converter (MWC) discrete compressed sampling (CS) structure, and we further propose a uniform linear array (ULA)-based MWC discrete CS structure to estimate the ...

Multichannel Sampling of Pulse Streams at the Rate of Innovation
, 2010 We consider minimal-rate sampling schemes for infinite streams of delayed and weighted versions of a known pulse shape. The minimal sampling rate for these parametric signals is referred to as the rate of innovation and is equal to the number of degrees ...

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.

Improved algorithm based on modulated wideband converter for multiband signal reconstruction [PDF]
EURASIP Journal on Wireless Communications and Networking, 2016 For the compressed sensing of multiband signals, modulated wideband converter (MWC) is used as the sampling system, and the signal is reconstructed by the simultaneous orthogonal matching pursuit algorithm (SOMP) and its derivative algorithms. In order to find matching atoms, we need to obtain the inner product between atoms in sensing matrix and ...

Advanced Functional Materials, EarlyView.This study investigates H4TBAPy‐based metal–organic frameworks (MOFs) ‐ NU‐1000, NU‐901, SrTBAPy, and BaTBAPy ‐ for multiphoton absorption (MPA) performance. It observes topology‐dependent variations in the 2PA cross‐section, with BaTBAPy exhibiting the highest activity.

Advanced Functional Materials, EarlyView.Controlled syntheses of lanthanide coordination polymers based on the dihydroxybenzoquinone (DHBQ) organic linker afforded large single crystals of Ln‐DHBQ CPs (Ln = Yb, Nd). A novel structural variant of Yb‐DHBQ is identified by means of single crystal diffraction analysis.

Sub-Nyquist Sampling: Bridging Theory and Practice [PDF]
, 2011 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 landmark in the development of digital signal processing. In modern applications,

Blind Sub-Nyquist Spectrum Sensing With Modulated Wideband Converter
IEEE Transactions on Vehicular Technology, 2018 Rooted in the compressed sensing theory, sub-Nyquist spectrum sensing (SNSS) has been considered as a promising approach to dealing with difficulties and limitations of conventional wideband spectrum sensing in cognitive radio (CR) networks. Most existing SNSS methods require some prior knowledge of the monitored frequency bands, such as the spectrum ...
