Sparse Joint Transmission for Cell-Free Massive MIMO: A Sparse PCA Approach
Deokhwan Han, Jeonghun Park, Namyoon Lee
Cell-free massive multiple-input multiple-output (MIMO) is a promising cellular network. In this network, a large number of distributed and multi-antenna access points (APs) jointl…
Supervised-Learning for Multi-Hop MU-MIMO Communications with One-Bit Transceivers
Daeun Kim, Song-Nam Hong, Namyoon Lee
This paper considers a nonlinear multi-hop multi-user multiple-input multiple-output (MU-MIMO) relay channel, in which multiple users send information symbols to a multi-antenna ba…
Robust Data Detection for MIMO Systems with One-Bit ADCs: A Reinforcement Learning Approach
Yo-Seb Jeon, Namyoon Lee, H. Vincent Poor
The use of one-bit analog-to-digital converters (ADCs) at a receiver is a power-efficient solution for future wireless systems operating with a large signal bandwidth and/or a mass…
Semi-Supervised Learning Detector for MU-MIMO Systems with One-bit ADCs
Seonho Kim, Song-Nam Hong
We study an uplink multiuser multiple-input multiple-output (MU-MIMO) system with one-bit analog-to-digital converters (ADCs). For such system, a supervised-learning (SL) detector…
Joint User Selection, Power Allocation, and Precoding Design with Imperfect CSIT for Multi-Cell MU-MIMO Downlink Systems
Jiwook Choi, Namyoon Lee, Song-Nam Hong +1
In this paper, a new optimization framework is presented for the joint design of user selection, power allocation, and precoding in multi-cell multi-user multiple-input multiple-ou…
