Precoding Design for Multi-user MIMO Systems with Delay-Constrained and -Tolerant Users
Minsu Kim, Jeonghun Park, Jemin Lee
In both academia and industry, multi-user multiple-input multiple-output (MU-MIMO) techniques have shown enormous gains in spectral efficiency by exploiting spatial degrees of free…
Non-Terrestrial Networks for UAVs: Base Station Service Provisioning Schemes with Antenna Tilt
Seongjun Kim, Minsu Kim, Jong Yeol Ryu +2
By focusing on unmanned aerial vehicle (UAV) communications in non-terrestrial networks (NTNs), this paper provides a guideline on the appropriate base station (BS) service provisi…
Securing Communications with Friendly Unmanned Aerial Vehicle Jammers
Minsu Kim, Seongjun Kim, Jemin Lee
In this paper, we analyze the impact of a friendly unmanned aerial vehicle (UAV) jammer on UAV communications in the presence of multiple eavesdroppers. We first present channel co…
Ensuring Data Freshness for Blockchain-enabled Monitoring Networks
Minsu Kim, Sungho Lee, Chanwon Park +2
The age of information (AoI) is a recently proposed metric for quantifying data freshness in real-time status monitoring systems where timeliness is of importance. In this paper, t…
