Free-Space Optical Communications for 6G Wireless Networks: Challenges, Opportunities, and Prototype Validation
Hong-Bae Jeon, Soo-Min Kim, Hyung-Joo Moon +6
Numerous researchers have studied innovations in future sixth-generation (6G) wireless communications. Indeed, a critical issue that has emerged is to contend with society's insati…
Performance Analysis of Self-Interference Cancellation in Full-Duplex Massive MIMO Systems: Subtraction versus Spatial Suppression
Soo-Min Kim, Yeon-Geun Lim, Linglong Dai +1
Massive multiple-input multiple-output (MIMO) and full-duplex (FD) are promising candidates for achieving the spectral efficiency to meet the needs of 5G communications. One essent…
Demo: A Transparent Antenna System for In-Building Networks
Sang-Hyun Park, Soo-Min Kim, Seonghoon Kim +3
For in-building networks, the potential of transparent antennas, which are used as windows of a building, is presented in this paper. In this scenario, a transparent window antenna…
Full Duplex Integrated Access and Backhaul for 5G NR: Analyses and Prototype Measurements
Gee Yong Suk, Soo-Min Kim, Jongwoo Kwak +3
Integrated access and backhaul (IAB) frameworks for 5G new radio (NR) as a cost-effective alternative to the wired backhaul have been investigated by 3GPP. A promising solution for…
Demo: A Unified Platform of Free-Space Optics for High-Quality Video Transmission
Hong-Bae Jeon, Hyung-Joo Moon, Soo-Min Kim +4
In this paper, we investigate video signal transmission through an FPGA-based free-space optical (FSO) communication system prototype. We use a channel emulator that models the tur…
Demo: A Reinforcement Learning-based Flexible Duplex System for B5G with Sub-6 GHz
Soo-Min Kim, Han Cha, Seong-Lyun Kim +1
In this paper, we propose a reinforcement learning-based flexible duplex system for B5G with Sub-6 GHz. This system combines full-duplex radios and dynamic spectrum access to maxim…
Opportunism in Dynamic Spectrum Access for 5G: A Concept and Its Application to Duplexing
Jeemin Kim, Soo-Min Kim, Han Cha +4
With the envisioned massive Internet-of-Things (IoT) era, one of the challenges for 5G wireless systems will be handling the unprecedented spectrum crunch. A potential solution has…
