Predicting Future CSI Feedback For Highly-Mobile Massive MIMO Systems
Yu Zhang, Ahmed Alkhateeb, Pranav Madadi +3
Massive multiple-input multiple-output (MIMO) system is promising in providing unprecedentedly high data rate. To achieve its full potential, the transceiver needs complete channel…
PolarDenseNet: A Deep Learning Model for CSI Feedback in MIMO Systems
Pranav Madadi, Jeongho Jeon, Joonyoung Cho +3
In multiple-input multiple-output (MIMO) systems, the high-resolution channel information (CSI) is required at the base station (BS) to ensure optimal performance, especially in th…
Wireless Network-Level Partial Relay Cooperation: A Stable Throughput Analysis
Nikolaos Pappas, Jeongho Jeon, Di Yuan +2
In this work, we study the benefit of partial relay cooperation. We consider a two-node system consisting of one source and one relay node transmitting information to a common dest…
Effect of Energy Harvesting on Stable Throughput in Cooperative Relay Systems
Nikolaos Pappas, Marios Kountouris, Jeongho Jeon +2
In this paper, the impact of energy constraints on a two-hop network with a source, a relay and a destination under random medium access is studied. A collision channel with erasur…
Channel-Aware Random Access in the Presence of Channel Estimation Errors
Jeongho Jeon, Anthony Ephremides
In this work, we consider the random access of nodes adapting their transmission probability based on the local channel state information (CSI) in a decentralized manner, which is…
On the Stability of Random Multiple Access with Stochastic Energy Harvesting
Jeongho Jeon, Anthony Ephremides
In this paper, we consider the random access of nodes having energy harvesting capability and a battery to store the harvested energy. Each node attempts to transmit the head-of-li…
Optimal Utilization of a Cognitive Shared Channel with a Rechargeable Primary Source Node
Nikolaos Pappas, Jeongho Jeon, Anthony Ephremides +1
This paper considers the scenario in which a set of nodes share a common channel. Some nodes have a rechargeable battery and the others are plugged to a reliable power supply and,…
