Coded Caching in a Multi-Server System with Random Topology
Nitish Mital, Deniz Gunduz, Cong Ling
Cache-aided content delivery is studied in a multi-server system with servers and users, each equipped with a local cache memory. In the delivery phase, each user connects…
Polar Coding for the Cognitive Interference Channel with Confidential Messages
Mengfan Zheng, Wen Chen, Cong Ling
In this paper, we propose a low-complexity, secrecy capacity achieving polar coding scheme for the cognitive interference channel with confidential messages (CICC) under the strong…
Hybrid Vector Perturbation Precoding: The Blessing of Approximate Message Passing
Shanxiang Lyu, Cong Ling
Vector perturbation (VP) precoding is a promising technique for multiuser communication systems operating in the downlink. In this work, we introduce a hybrid framework to improve…
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…
AWGN-Goodness is Enough: Capacity-Achieving Lattice Codes based on Dithered Probabilistic Shaping
Antonio Campello, Daniel Dadush, Cong Ling
In this paper we show that any sequence of infinite lattice constellations which is good for the unconstrained Gaussian channel can be shaped into a capacity-achieving sequence of…
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…
