Considered in this paper is a single-carrier asynchronous bidirectional cooperative network with amplify-and-forward relays helping two transceivers to exchange information. The network is asynchronous in the sense that the delays of propagation alon

The problem of resource provisioning and content placement in cloud-based content delivery networks is studied, and a two-stage resource provisioning and cloud assignment is proposed based on dynamic large and small-scale fluctuations of user demand

Ultrasonic imaging of multi-layer materials with parallel interfaces is a challenging problem in non-destructive testing. In multi-layer materials, since the sound velocity and the propagation path change when sound travels from one layer into anothe

The problem of cloud resource optimization is examined, while the uncertainty in demand and user feedback is considered. We propose a Markov decision process model for resource assignment in cloud-based content delivery networks. Furthermore, we incl

In a distributed massive multiple-input multiple-output (DM-MIMO) system, a large number of antennas are distributed across multiple remote radio heads (RRHs) within the coverage area. Distributing antennas is an appealing approach to provide fairly

We study the sum-rate maximization problem, under a total power budget, for asynchronous single-carrier bi-directional relay networks, consisting of two transceivers and multiple amplify-and-forward relays. When different transceiver-relay links caus

We study the total transmit power minimization problem for a two-way relay network under two constraints on the transceivers' received signal-to-noise-ratios. The network considered herein consists of multiple multi-antenna relay nodes and two single
