On Covert Communication with Noise Uncertainty
Biao He, Shihao Yan, Xiangyun Zhou +1
Prior studies on covert communication with noise uncertainty adopted a worst-case approach from the warden's perspective. That is, the worst-case detection performance of the warde…
Cache-induced Hierarchical Cooperation in Wireless Device-to-Device Caching Networks
An Liu, Vincent Lau, Giuseppe Caire
We consider a wireless device-to-device (D2D) caching network where n nodes are placed on a regular grid of area A(n). Each node caches L_C*F (coded) bits from a library of size L*…
On the Design of Secure Non-Orthogonal Multiple Access Systems
Biao He, An Liu, Nan Yang +1
This paper proposes a new design of non-orthogonal multiple access (NOMA) under secrecy considerations. We focus on a NOMA system where a transmitter sends confidential messages to…
Distributed Stochastic Optimization for Weakly Coupled Systems with Applications to Wireless Communications
Fan Zhang, Ying Cui, Vincent K. N. Lau +1
In this paper, a framework is proposed to simplify solving the infinite horizon average cost problem for the weakly coupled multi-dimensional systems. Specifically, to address the…
Networked Control Systems over Correlated Wireless Fading Channels
Fan Zhang, Vincent K. N. Lau, Ling Shi
In this paper, we consider a networked control system (NCS) in which an dynamic plant system is connected to a controller via a temporally correlated wireless fading channel. We fo…
How Much Cache is Needed to Achieve Linear Capacity Scaling in Backhaul-Limited Dense Wireless Networks?
An Liu, Vincent Lau
Dense wireless networks are a promising solution to meet the huge capacity demand in 5G wireless systems. However, there are two implementation issues, namely the interference and…
