Multi-IRS-assisted Multi-Cell Uplink MIMO Communications under Imperfect CSI: A Deep Reinforcement Learning Approach
Junghoon Kim, Seyyedali Hosseinalipour, Taejoon Kim +2
Applications of intelligent reflecting surfaces (IRSs) in wireless networks have attracted significant attention recently. Most of the relevant literature is focused on the single…
Delay-Efficient and Reliable Data Relaying in Ultra Dense Networks using Rateless Codes
Luyao Shang, Morteza Hashemi, Taejoon Kim +1
We investigate the problem of delay-efficient and reliable data delivery in ultra-dense networks (UDNs) that constitute macro base stations (MBSs), small base stations (SBSs), and…
Enhanced Beam Alignment for Millimeter Wave MIMO Systems: A Kolmogorov Model
Qiyou Duan, Taejoon Kim, Hadi Ghauch
We present an enhancement to the problem of beam alignment in millimeter wave (mmWave) multiple-input multiple-output (MIMO) systems, based on a modification of the machine learnin…
Minimum Overhead Beamforming and Resource Allocation in D2D Edge Networks
Junghoon Kim, Taejoon Kim, Morteza Hashemi +2
Device-to-device (D2D) communications is expected to be a critical enabler of distributed computing in edge networks at scale. A key challenge in providing this capability is the r…
A Sequential Subspace Method for Millimeter Wave MIMO Channel Estimation
Wei Zhang, Taejoon Kim, Shu-Hung Leung
Data transmission over the mmWave in fifth-generation wireless networks aims to support very high speed wireless communications. A substantial increase in spectrum efficiency for m…
Joint Optimization of Signal Design and Resource Allocation in Wireless D2D Edge Computing
Junghoon Kim, Taejoon Kim, Morteza Hashemi +2
In this paper, we study the distributed computational capabilities of device-to-device (D2D) networks. A key characteristic of D2D networks is that their topologies are reconfigura…
