Energy-Efficient Secure Offloading System Designed via UAV-Mounted Intelligent Reflecting Surface for Resilience Enhancement
Doyoung Kim, Seongah Jeong, Jinkyu Kang
With increasing interest in mmWave and THz communication systems, an unmanned aerial vehicle (UAV)-mounted intelligent reflecting surface (IRS) has been suggested as a key enabling…
Transceiver Design and Performance Analysis for LR-FHSS-based Direct-to-Satellite IoT
Sooyeob Jung, Seongah Jeong, Jinkyu Kang +2
This paper presents a novel transceiver design aimed at enabling Direct-to-Satellite Internet of Things (DtS-IoT) systems based on long range-frequency hopping spread spectrum (LR-…
Marine IoT Systems with Space-Air-Sea Integrated Networks: Hybrid LEO and UAV Edge Computing
Sooyeob Jung, Seongah Jeong, Jinkyu Kang +1
Marine Internet of Things (IoT) systems have grown substantially with the development of non-terrestrial networks (NTN) via aerial and space vehicles in the upcoming sixth-generati…
Control-Data Separation with Decentralized Edge Control in Fog-Assisted Uplink Communications
Jinkyu Kang, Osvaldo Simeone, Joonhyuk Kang +1
Fog-aided network architectures for 5G systems encompass wireless edge nodes, referred to as remote radio systems (RRSs), as well as remote cloud center (RCC) processors, which are…
On the Trade-Off between Computational Load and Reliability for Network Function Virtualization
Jinkyu Kang, Osvaldo Simeone, Joonhyuk Kang
Network Function Virtualization (NFV) enables the "softwarization" of network functions, which are implemented on virtual machines hosted on Commercial off-the-shelf (COTS) servers…
Cloud Radio Access Networks: Uplink Channel Estimation and Downlink Precoding
Osvaldo Simeone, Jinkyu Kang, Joonhyuk Kang +1
The gains afforded by cloud radio access network (C-RAN) in terms of savings in capital and operating expenses, flexibility, interference management and network densification rely…
Control-Data Separation across Edge and Cloud for Uplink Communications in C-RAN
Jinkyu Kang, Osvaldo Simeone, Joonhyuk Kang +1
Fronthaul limitations in terms of capacity and latency motivate the growing interest in the wireless industry for the study of alternative functional splits between cloud and edge…
Layered Downlink Precoding for C-RAN Systems with Full Dimensional MIMO
Jinkyu Kang, Osvaldo Simeone, Joonhyuk Kang +1
The implementation of a Cloud Radio Access Network (C-RAN) with Full Dimensional (FD)-MIMO is faced with the challenge of controlling the fronthaul overhead for the transmission of…
Fronthaul Compression and Precoding Design for C-RANs over Ergodic Fading Channel
Jinkyu Kang, Osvaldo Simeone, Joonhyuk Kang +1
This work investigates the joint design of fronthaul compression and precoding for the downlink of Cloud Radio Access Networks (C-RANs). In a C-RAN, a central unit (CU) performs th…
Joint Signal and Channel State Information Compression for the Backhaul of Uplink Network MIMO Systems
Jinkyu Kang, Osvaldo Simeone, Joonhyuk Kang +1
In network MIMO cellular systems, subsets of base stations (BSs), or remote radio heads, are connected via backhaul links to central units (CUs) that perform joint encoding in the…
