Beam Squint in Ultra-wideband mmWave Systems: RF Lens Array vs. Phase-Shifter-Based Array
Sang-Hyun Park, Byoungnam Kim, Dong Ku Kim +3
In this article, we discuss the potential of radio frequency (RF) lens for ultra-wideband millimeter-wave (mmWave) systems. In terms of the beam squint, we compare the proposed RF…
Meta-Reinforcement Learning Based Resource Allocation for Dynamic V2X Communications
Yi Yuan, Gan Zheng, Kai-Kit Wong +1
This paper studies the allocation of shared resources between vehicle-to-infrastructure (V2I) and vehicle-to-vehicle (V2V) links in vehicle-to-everything (V2X) communications. In e…
Embedding Model Based Fast Meta Learning for Downlink Beamforming Adaptation
Juping Zhang, Yi Yuan, Gan Zheng +2
This paper studies the fast adaptive beamforming for the multiuser multiple-input single-output downlink. Existing deep learning-based approaches assume that training and testing c…
Learning from Images: Proactive Caching with Parallel Convolutional Neural Networks
Yantong Wang, Ye Hu, Zhaohui Yang +3
With the continuous trend of data explosion, delivering packets from data servers to end users causes increased stress on both the fronthaul and backhaul traffic of mobile networks…
Achievable Regions and Precoder Designs for the Multiple Access Wiretap Channels with Confidential and Open Messages
Hao Xu, Tianyu Yang, Kai-Kit Wong +1
This paper investigates the secrecy capacity region of multiple access wiretap (MAC-WT) channels where, besides confidential messages, the users have also open messages to transmit…
Enhancing and Localizing Surface Wave Propagation with Reconfigurable Surfaces
Z. Chu, K. K. Wong, K. F. Tong
As an attempt to develop a reconfigurable surface architecture that can use liquid metal such as Galinstan to shape surface channels on demand, this paper considers a punctured sur…
