Caching Placement in Stochastic Wireless Caching Helper Networks: Channel Selection Diversity via Caching
Seong Ho Chae, Wan Choi
Content delivery success in wireless caching helper networks depends mainly on cache-based channel selection diversity and network interference. For given channel fading and networ…
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…
Optimal Storage Allocation for Wireless Cloud Caching Systems with a Limited Sum Storage Capacity
Bi Hong, Wan Choi
In wireless cloud storage systems, the recovery failure probability depends on not only wireless channel conditions but also storage size of each distributed storage node. For an e…
