Device Activity Detection for Massive Grant-Free Access Under Frequency-Selective Rayleigh Fading
Yuhang Jia, Ying Cui, Wuyang Jiang
Device activity detection and channel estimation for massive grant-free access under frequency-selective fading have unfortunately been an outstanding problem. This paper aims to a…
Statistical Device Activity Detection for OFDM-based Massive Grant-Free Access
Yuhang Jia, Ying Cui, Wuyang Jiang
Existing works on grant-free access, proposed to support massive machine-type communication (mMTC) for the Internet of things (IoT), mainly concentrate on narrow band systems under…
Robust Optimization of Instantaneous Beamforming and Quasi-static Phase Shifts in an IRS-assisted Multi-Cell Network
Yuhang Jia, Ying Cui, Wuyang Jiang
The impacts of channel estimation errors, inter-cell interference, phase adjustment cost, and computation cost on an intelligent reflecting surface (IRS)-assisted system are severe…
Low-complexity Robust Optimization for an IRS-assisted Multi-Cell Network
Yuhang Jia, Wuyang Jiang, Ying Cui
The impacts of channel estimation errors, inter-cell interference, phase adjustment cost, and computation cost on an intelligent reflecting surface (IRS)-assisted system are severe…
Analysis and Optimization of an Intelligent Reflecting Surface-assisted System with Interference
Yuhang Jia, Chencheng Ye, Ying Cui
In this paper, we study an intelligent reflecting surface (IRS)-assisted system where a multi-antenna base station (BS) serves a single-antenna user with the help of a multi-elemen…
