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.

Hardware Design of DC-3GHz Compressed Sensing Receiver Based on Modulated Wideband Converter
IEEE International RF and Microwave Conference, 2018Modulated Wideband Converter (MWC) is a sub-Nyquist sampling structure suitable for wideband sparse signals. Based on MWC, this paper designs a DC-3 GHz Compressed Sensing (CS) receiver system with commercial devices.

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.

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.

A New Compensating Method of Non-Ideal Lowpass Filters in Modulated Wideband Converter
International Conference on Instrumentation and Measurement, Computer, Communication and Control, 2018There are several non-ideal factors in the hardware implementation of Modulated Wideband Converter (MWC), which is an efficient sub-Nyquist system for sampling the sparse multiband signals.

Analysis and Signal Recovery of Modulated Wideband Converter with Gain Mismatch
Applied Mechanics and Materials, 2013Recently, 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.

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 ...

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.
