Secrecy Rate Maximization for Intelligent Reflecting Surface Assisted Multi-Antenna Communications
Hong Shen, Wei Xu, Shulei Gong +2
We investigate transmission optimization for intelligent reflecting surface (IRS) assisted multi-antenna systems from the physical-layer security perspective. The design goal is to…
Rethinking Uplink Hybrid Processing: When is Pure Analog Processing Suggested?
Jingbo Du, Wei Xu, Bin Sheng +1
In this correspondence, we analytically characterize the benefit of digital processing in uplink massive multiple-input multiple-output (MIMO) with sub-connected hybrid architectur…
Hybrid Transceiver Optimization for Multi-Hop Communications
Chengwen Xing, Xin Zhao, Shuai Wang +3
Multi-hop communication with the aid of large-scale antenna arrays will play a vital role in future emergence communication systems. In this paper, we investigate amplify-and-forwa…
Effective Capacity and Power Allocation for Machine-Type Communication
Mohammad Shehab, Hirley Alves, Matti Latva-aho
Effective capacity (EC) determines the maximum communication rate subject to a particular delay constraint. In this work, we analyze the EC of ultra reliable Machine Type Communica…
Optimal Multiuser Loading in Quantized Massive MIMO under Spatially Correlated Channels
Jindan Xu, Wei Xu, Fengkui Gong +2
Low-resolution digital-to-analog converter (DAC) has shown great potential in facilitating cost- and power-efficient implementation of massive multiple-input multiple-output (MIMO)…
Secure Massive MIMO Communication with Low-resolution DACs
Jindan Xu, Wei Xu, Jun Zhu +2
In this paper, we investigate secure transmission in a massive multiple-input multiple-output (MIMO) system adopting low-resolution digital-to-analog converters (DACs). Artificial…
