Block Orthogonal Sparse Superposition Codes for Ultra-Reliable Low-Latency Communications
Donghwa Han, Jeonghun Park, Youngjoo Lee +2
Low-rate and short-packet transmissions are important for ultra-reliable low-latency communications (URLLC). In this paper, we put forth a new family of sparse superposition codes…
Joint Precoding and Artificial Noise Design for MU-MIMO Wiretap Channels
Eunsung Choi, Mintaek Oh, Jinseok Choi +3
Secure precoding superimposed with artificial noise (AN) is a promising transmission technique to improve security by harnessing the superposition nature of the wireless medium. Ho…
Coverage Analysis of LEO Satellite Downlink Networks: Orbit Geometry Dependent Approach
Junse Lee, Song Noh, Sooyeob Jeong +1
The low-earth-orbit (LEO) satellite network with mega-constellations can provide global coverage while supporting the high-data rates. The coverage performance of such a network is…
Communication-Efficient Federated Learning over MIMO Multiple Access Channels
Yo-Seb Jeon, Mohammad Mohammadi Amiri, Namyoon Lee
Communication efficiency is of importance for wireless federated learning systems. In this paper, we propose a communication-efficient strategy for federated learning over multiple…
