On the Feasibility of Full-duplex Large-scale MIMO Cellular Systems
Jeongwan Koh, Yeon-Geun Lim, Chan-Byoung Chae +1
This paper concerns the feasibility of full-duplex large-scale multiple-input-multiple-output (MIMO) cellular systems. We first propose a pilot transmission scheme and assess its p…
Map-based Millimeter-Wave Channel Models: An Overview, Hybrid Modeling, Data, and Learning
Yeon-Geun Lim, Yae Jee Cho, MinSoo Sim +3
Compared to the current wireless communication systems, millimeter wave (mm-Wave) promises a wide range of spectrum. As viable alternatives to existing mm-Wave channel models, vari…
Relationship between Cross-Polarization Discrimination (XPD) and Spatial Correlation in Indoor Small-Cell MIMO Systems
Yeon-Geun Lim, Yae Jee Cho, TaeckKeun Oh +2
In this letter, we present a correlated channel model for a dual-polarization antenna to omnidirectional antennas in indoor small-cell multiple-input multiple-output (MIMO) systems…
Multiple Access for 5G New Radio: Categorization, Evaluation, and Challenges
Hyunsoo Kim, Yeon-Geun Lim, Chan-Byoung Chae +1
Next generation wireless networks require massive uplink connections as well as high spectral efficiency. It is well known that, theoretically, it is not possible to achieve the su…
