Efficient Recovery of Block Sparse Signals via Zero-point Attracting Projection
Jingbo Liu, Jian Jin, Yuantao Gu
In this paper, we consider compressed sensing (CS) of block-sparse signals, i.e., sparse signals that have nonzero coefficients occurring in clusters. An efficient algorithm, calle…

Quantization Reference Voltage of the Modulated Wideband Converter
Yaming Wang, Laming Chen, Yuantao Gu
The Modulated Wideband Converter (MWC) is a recently proposed analog-to-digital converter (ADC) based on Compressive Sensing (CS) theory. Unlike conventional ADCs, its quantization…
