A calibration system and perturbation analysis for the Modulated Wideband Converter
IEEE 10th INTERNATIONAL CONFERENCE ON SIGNAL PROCESSING PROCEEDINGS, 2010A calibration system is proposed in this paper for the Modulated Wideband Converter (MWC), which is an efficient sampling system for the sparse multiband signals. The proposed calibration system has the ability to acquire actual measurement matrix and is achievable both in its structure and in its computational complexity.

The effect of modulated wideband converter placement on compressive spectrum sensing
2013 IEEE Antennas and Propagation Society International Symposium (APSURSI), 2013The modulated wideband converter (MWC) introduced in [1] enables a wide band of spectrum to be sensed using inexpensive components. The MWC spreads the received signal in frequency, which allows the spectral occupancy to be sensed from sub-Nyquist rate samples via compressive sensing techniques.

Wideband modeling and transient analysis of sub-module in modular multilevel converter
COMPEL - The international journal for computation and mathematics in electrical and electronic engineering, 2017Purpose This paper aims to establish the wideband model of a sub-module in a modular multilevel converter (MMC) and analyze the switch transients of the sub-module. Design/methodology/approach The paper builds an MMC sub-module test circuit and conducts dynamic tests both with and without the bypass thyristor.

A new approach to near-theoretical sampling rate for modulated wideband converter
2014 International Conference on Signal Processing and Communications (SPCOM), 2014For 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 ...

Frequency spectrum analysis of compressed sampling datum based on modulated wideband converter
2016 IEEE Information Technology, Networking, Electronic and Automation Control Conference, 2016In order to reduce the computational complexity of frequency spectrum analysis, we aim to investigate spectrum directly from compressed sampling datum based on Modulated Wideband Converter (MWC) principle without using sparse reconstruction operation. Due to better performance of processing multiband signal, MWC is the most successful architecture of ...

The design of a novel wideband up-converter module in millimeter wave
2016 CIE International Conference on Radar (RADAR), 2016In this paper, a novel wideband up-converter module applied in millimeter wave is proposed. The local signal (LO) of 13∼17GHz is feed into an active multiplier through a SMA connector, and the output signal of 26∼34GHz is then mixed with an intermediate frequency signal (IF) of 6GHz±0.5GHz through another SMA connector.

On a new compressed sensing paradigm in the modulated wideband converter
Eurocon 2013, 2013Concerning sub-Nyquist sampling, this paper continues research on the modulated wideband converter (MWC), which uses compressed sensing (CS) to sample multiband signals with unknown carriers below their Nyquist rate. The minimum sampling rate for blind acquisition of these signals is 2NB, with N the number of bands and B their bandwidth.

Spectrum Sensing Based on Modulated Wideband Converter with CoSaMP Reconstruction Algorithm
2017Modulated Wideband Converter (MWC) provides a sub-Nyquist sampling approach for wideband spectrum sensing. In previous studies, reconstruction algorithm, OMP (Orthogonal Matching Pursuit) is used in the CTF (continuous-to-finite) block of MWC for frequency support recovery.
