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…
Energy Efficiency Maximization Precoding for Quantized Massive MIMO Systems
Jinseok Choi, Jeonghun Park, Namyoon Lee
The use of low-resolution digital-to-analog and analog-to-digital converters (DACs and ADCs) significantly benefits energy efficiency (EE) at the cost of high quantization noise in…
Sparse Joint Transmission for Cloud Radio Access Networks with Limited Fronthaul Capacity
Deokhwan Han, Jeonghun Park, Seok-Hwan Park +1
A cloud radio access network (C-RAN) is a promising cellular network, wherein densely deployed multi-antenna remote-radio-heads (RRHs) jointly serve many users using the same time-…
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…
Terahertz Line-Of-Sight MIMO Communication: Theory and Practical Challenges
Heedong Do, Sungmin Cho, Jeonghun Park +3
A relentless trend in wireless communications is the hunger for bandwidth, and fresh bandwidth is only to be found at ever-higher frequencies. While 5G systems are seizing the mmWa…
Rate Analysis of Ultra-Reliable Low-Latency Communications in Random Wireless Networks
Jeonghun Park
In this letter, we analyze the achievable rate of ultra-reliable low-latency communications (URLLC) in a randomly modeled wireless network. We use two mathematical tools to properl…
