A User's Guide to Compressed Sensing for Communications Systems
TL;DR: The problem of compressed sensing is considered as an underdetermined linear system with a prior information that the true solution is sparse, and the sparse signal recovery is explained based on � 1 optimization, which plays the central role in compressed sensing.
Journal ArticleDOI
Maximum Hands-Off Control: A Paradigm of Control Effort Minimization
TL;DR: In this article, the maximum hands-off control is defined as the minimum support (or sparsest) per unit time among all control objectives that achieve control objectives, and the equivalence between the maximum handoff control and the optimal control under a uniqueness assumption called normality is shown.
Journal ArticleDOI
Sparse Packetized Predictive Control for Networked Control Over Erasure Channels
TL;DR: It is shown how to design the tuning parameters to ensure (practical) stability of the resulting feedback control systems when the number of consecutive packet-dropouts is bounded.
Journal ArticleDOI
Frequency Domain Min-Max Optimization of Noise-Shaping Delta-Sigma Modulators
Masaaki Nagahara,Yutaka Yamamoto +1 more
TL;DR: A min-max design of noise-shaping delta-sigma modulators with general quantizers including uniform ones is proposed, which minimizes the worst-case reconstruction error, and hence improves the SNR (signal-to-noise ratio) of the modulator.
Journal ArticleDOI
Discrete Signal Reconstruction by Sum of Absolute Values
TL;DR: In this paper, the authors consider a problem of reconstructing an unknown discrete signal taking values in a finite alphabet from incomplete linear measurements, and propose to solve the problem by minimizing the sum of weighted absolute values.
