Learned Trimmed-Ridge Regression for Channel Estimation in Millimeter-Wave Massive MIMO
Pengxia Wu, Julian Cheng, Yonina C. Eldar +1
Channel estimation poses significant challenges in millimeter-wave massive multiple-input multiple-output systems, especially when the base station has fewer radio-frequency chains…
CubeSat-Enabled Free-Space Optics: Joint Data Communication and Fine Beam Tracking
Hossein Safi, Mohammad Taghi Dabiri, Julian Cheng +2
The integration of CubeSats with Free Space Optical (FSO) links accelerates a major advancement in high-throughput, low-Earth orbit communication systems. However, CubeSats face ch…
Federated Deep Reinforcement Learning for RIS-Assisted Indoor Multi-Robot Communication Systems
Ruyu Luo, Wanli Ni, Hui Tian +1
Indoor multi-robot communications face two key challenges: one is the severe signal strength degradation caused by blockages (e.g., walls) and the other is the dynamic environment…
Ultrasonic Backscatter Communication for Implantable Medical Devices
Qianqian Wang, Quansheng Guan, Julian Cheng +1
This paper proposes an ultrasonic backscatter communication (UsBC) system for passive implantable medical devices (IMDs) that can operate without batteries, enabling versatile revo…
Ergodic Capacity of High Throughput Satellite Systems With Mixed FSO-RF Transmission
Kong Huaicong, Lin Min, Wang Zining +2
We study a high throughput satellite system, where the feeder link uses free-space optical (FSO) and the user link uses radio frequency (RF) communication. In particular, we first…
A High Coverage Camera Assisted Received Signal Strength Ratio Algorithm for Indoor Visible Light Positioning
Lin Bai, Yang Yang, Chunyan Feng +2
In this paper, a high coverage algorithm termed enhanced camera assisted received signal strength ratio (eCA-RSSR) positioning algorithm is proposed for visible light positioning (…
