Virtual MIMO in Multi-Cell Distributed Antenna Systems: Coordinated Transmissions with Large-Scale CSIT
TL;DR: The proposed coordinated transmissions with large-scale CSIT in DASs shed some light on virtual MIMO in the making by appealing to the successive approximation method and the saddle-point theory of concave-convex functions.
Proceedings ArticleDOI
Downlink Power Allocation for Distributed Antenna Systems in a Multi-Cell Environment
TL;DR: The downlink performance of distributed antenna systems (DAS) in a multi-cell environment is investigated and a simple sub-optimal power allocation scheme is proposed by substituting the approximation for the objective function.
Journal ArticleDOI
Hybrid Satellite-Terrestrial Communication Networks for the Maritime Internet of Things: Key Technologies, Opportunities, and Challenges
TL;DR: A survey on the demand for maritime communications enabled by state-of-the-art hybrid satellite-terrestrial maritime communication networks (MCNs), and envision the use of external auxiliary information to build up an environment-aware, service-driven, and integrated satellite-air-ground MCN.
Journal ArticleDOI
Maritime Coverage Enhancement Using UAVs Coordinated With Hybrid Satellite-Terrestrial Networks
TL;DR: Simulation results demonstrate that the UAV fits well with existing satellite and terrestrial systems, using the proposed optimization framework, and is deployed for coverage enhancement of a hybrid satellite-terrestrial maritime communication network.
Journal ArticleDOI
When mmWave Communications Meet Network Densification: A Scalable Interference Coordination Perspective
TL;DR: In this article, a large-scale channel state information (CSI) based interference coordination approach was proposed to solve the problem of co-channel interference under a network-level perspective, and a greedy scheme with polynomial-time complexity was proposed by adopting the bisection method and linear integer programming tools.
