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

Multiband signal acquisition using improved modulated wideband converter
The Journal of Engineering, 2019 In this study, the authors stress the problem of sampling and recovering sparse wideband signals. A new methodology for sparse multiband signal acquisition using sinusoidal frequency modulation (SMF) multiplier‐based modulated wideband converter (MWC) is presented. The harmonic property of the SMF signals enables sparse multiband signal to be precisely
