Modeling and Measurements for Multi-path Mitigation with Reconfigurable Intelligent Surfaces
Ruya Zhou, Xiangyu Chen, Wankai Tang +5
A reconfigurable intelligent surface (RIS) is capable of manipulating electromagnetic waves with its flexibly configurable unit cells, thus is an appealing technology to resist fas…
Asymmetrical Uplink and Downlink Transceivers in Massive MIMO Systems
Xi Yang, Shi Jin, Geoffrey Ye Li +1
Even if massive multiple-input multiple-output (MIMO) can theoretically bring huge benefits, it incurs substantial hardware complexity and expensive hardware costs. To address thes…
Channel Customization for Joint Tx-RISs-Rx Design in Hybrid mmWave Systems
Weicong Chen, Chao-Kai Wen, Xiao Li +1
In strong line-of-sight millimeter-wave (mmWave) wireless systems, the rank-deficient channel severely hampers spatial multiplexing. To address this inherent deficiency, multiple r…
Enabling Plug-and-Play and Crowdsourcing SLAM in Wireless Communication Systems
Jie Yang, Chao-Kai Wen, Shi Jin +1
Simultaneous localization and mapping (SLAM) during communication is emerging. This technology promises to provide information on propagation environments and transceivers' locatio…
3-D Deployment of UAV Swarm for Massive MIMO Communications
Ning Gao, Xiao Li, Shi Jin +1
We consider the uplink transmission between a multi-antenna ground station and an unmanned aerial vehicle (UAV) swarm. The UAVs are assumed as intelligent agents, which can explore…
Hybrid Beamforming for mmWave MU-MISO Systems Exploiting Multi-agent Deep Reinforcement Learning
Qisheng Wang, Xiao Li, Shi Jin +1
In this letter, we investigate the hybrid beamforming based on deep reinforcement learning (DRL) for millimeter Wave (mmWave) multi-user (MU) multiple-input-single-output (MISO) sy…
Interplay between RIS and AI in Wireless Communications: Fundamentals, Architectures, Applications, and Open Research Problems
Jinghe Wang, Wankai Tang, Yu Han +5
