A Tractable Approach to Coverage Analysis in Downlink Satellite Networks
Jeonghun Park, Jinseok Choi, Namyoon Lee
Satellite networks are promising to provide ubiquitous and high-capacity global wireless connectivity. Traditionally, satellite networks are modeled by placing satellites on a grid…
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…
Rate-Splitting Multiple Access for Downlink MIMO: A Generalized Power Iteration Approach
Jeonghun Park, Jinseok Choi, Namyoon Lee +2
Rate-splitting multiple access (RSMA) is a general multiple access scheme for downlink multi-antenna systems embracing both classical spatial division multiple access and more rece…
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…
