Secure Transmission for Hierarchical Information Accessibility in Downlink MU-MIMO
Kanguk Lee, Jinseok Choi, Dong Ku Kim +1
Physical layer security is a useful tool to prevent confidential information from wiretapping. In this paper, we consider a generalized model of conventional physical layer securit…
Ultrareliable and Low-Latency Communication Techniques for Tactile Internet Services
Kwang Soon Kim, Dong Ku Kim, Chan-Byoung Chae +9
This paper presents novel ultrareliable and low-latency communication (URLLC) techniques for URLLC services, such as Tactile Internet services. Among typical use-cases of URLLC ser…
RF Lens-Embedded Antenna Array for mmWave MIMO: Design and Performance
Yae Jee Cho, Gee-Yong Suk, Byoungnam Kim +2
The requirement of high data-rate in the fifth generation wireless systems (5G) calls for the ultimate utilization of the wide bandwidth in the mmWave frequency band. Researchers s…
Generalized Distributed Compressive Sensing
Jeonghun Park, Seunggye Hwang, Janghoon Yang +1
Distributed Compressive Sensing (DCS) improves the signal recovery performance of multi signal ensembles by exploiting both intra- and inter-signal correlation and sparsity structu…
An Approximation of the Outage Probability for Multi-hop AF Fixed Gain Relay
Jun Kyoung Lee, Janghoon Yang, Dong Ku Kim
In this letter, we present a closed-form approximation of the outage probability for the multi-hop amplify-and-forward (AF) relaying systems with fixed gain in Rayleigh fading chan…
