Mobility-Aware Content Placement for Device-to-Device Caching Systems
Jaeyoung Song, Wan Choi
User mobility has a large effect on optimal content placement in D2D caching networks. Since a typical user can communicate neighboring users who stay in the D2D communication area…
Communication and Consensus Co-Design for Distributed, Low-Latency and Reliable Wireless Systems
Hyowoon Seo, Jihong Park, Mehdi Bennis +1
Designing distributed, fast and reliable wireless consensus protocols is instrumental in enabling mission-critical decentralized systems, such as robotic networks in the industrial…
Beamforming Design for Full-Duplex Two-Way Amplify-and-Forward MIMO Relay
Yeonggyu Shim, Wan Choi, Hyuncheol Park
We consider the full-duplex (FD) two-way amplify-and-forward relay system with imperfect cancelation of loopback self-interference (SI) and investigate joint design of relay and re…
Beamforming for Full-Duplex Multiuser MIMO Systems
Jinwoo Kim, Wan Choi, Hyuncheol Park
We solve a sum rate maximization problem of full-duplex (FD) multiuser multiple-input multiple-output (MU-MIMO) systems. Since additional self-interference (SI) in the uplink chann…
Ergodic Interference Alignment with Delayed Feedback
Myung Gil Kang, Wan Choi
We propose new ergodic interference alignment techniques for -user interference channels with delayed feedback. Two delayed feedback scenarios are considered -- delayed channel…
