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…
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…
Dual Link Algorithm for the Weighted Sum Rate Maximization in MIMO Interference Channels
Xing Li, Seungil You, Lijun Chen +3
MIMO interference network optimization is important for increasingly crowded wireless communication networks. We provide a new algorithm, named Dual Link algorithm, for the classic…
