Coprime Sensing via Chinese Remaindering over Quadratic Fields, Part I: Array Designs
Conghui Li, Lu Gan, Cong Ling
A coprime antenna array consists of two or more sparse subarrays featuring enhanced degrees of freedom (DOF) and reduced mutual coupling. This paper introduces a new class of plana…
The Gap of Semantic Parsing: A Survey on Automatic Math Word Problem Solvers
Dongxiang Zhang, Lei Wang, Luming Zhang +2
Solving mathematical word problems (MWPs) automatically is challenging, primarily due to the semantic gap between human-readable words and machine-understandable logics. Despite th…
Atomic Norm Denoising-Based Joint Channel Estimation and Faulty Antenna Detection for Massive MIMO
Peng Zhang, Lu Gan, Cong Ling +1
We consider joint channel estimation and faulty antenna detection for massive multiple-input multiple-output (MIMO) systems operating in time-division duplexing (TDD) mode. For sys…
Uniform Recovery Bounds for Structured Random Matrices in Corrupted Compressed Sensing
Peng Zhang, Lu Gan, Cong Ling +1
We study the problem of recovering an -sparse signal from corrupted measurements $\mathbf{y} = \mathbf{A}\mathbf{x}^{\star}+\mathbf{z}^{\star…
Modulated Unit-Norm Tight Frames for Compressed Sensing
Peng Zhang, Lu Gan, Sumei Sun +1
In this paper, we propose a compressed sensing (CS) framework that consists of three parts: a unit-norm tight frame (UTF), a random diagonal matrix and a column-wise orthonormal ma…
Deterministic Sequences for Compressive MIMO Channel Estimation
Peng Zhang, Lu Gan, Sumei Sun +1
This paper considers the problem of pilot design for compressive multiple-input multiple-output (MIMO) channel estimation. In particular, we are interested in estimating the channe…
