On Secure NOMA-CDRT Systems with Physical Layer Network Coding
Hongjiang Lei, Xusheng She, Ki-Hong Park +4
This paper proposes a new scheme to enhance the secrecy performance of a NOMA-based coordinated direct relay transmission system (NOMA-CDRT) with an untrusted relay. The physical-l…
Joint Trajectory Design and User Scheduling of Aerial Cognitive Radio Networks
Hongjiang Lei, Haosi Yang, Ki-Hong Park +3
Unmanned aerial vehicles (UAVs) have been widely employed to enhance the end-to-end performance of wireless communications since the links between UAVs and terrestrial nodes are li…
On-Demand Networking for Ubiquitous Connectivity and Network Resilience: A Network-in-a-Box Solution
Ki-Hong Park, Mohamed-Slim Alouini, Yunfei Chen
Recently, the wireless community has initiated research on the sixth generation (6G) cellular network for the next decade. The 6G visions are still under development but are conver…
Statistical Modeling of the Impact of Underwater Bubbles on an Optical Wireless Channel
Myoungkeun Shin, Ki-Hong Park, Mohamed-Slim Alouini
In underwater wireless optical communications (UWOC), the random obstruction of light propagation by air bubbles can cause fluctuations in the incoming light intensity of a receive…
Throughput Maximization of Mixed FSO/RF UAV-aided Mobile Relaying with a Buffer
Ju-Hyung Lee, Ki-Hong Park, Young-Chai Ko +1
In this paper, we consider an unmanned aerial vehicle (UAV) aided mobile relaying system under a buffer constraint. We propose a new relaying protocol employing mixed free-space op…
A UAV-Mounted Free Space Optical Communication: Trajectory Optimization for Flight Time
Ju-Hyung Lee, Ki-Hong Park, Young-Chai Ko +1
In this work, we address the trajectory optimization of a fixed-wing unmanned aerial vehicle (UAV) using free space optical communication (FSOC). Here, we focus on maximizing the f…
