In this paper, we focus on the design of an optimal power allocation algorithm and an efficient user selection scheme for the downlink of a non-orthogonal multiple access (NOMA) system with power-d

Recently, the duality between multiple-input multiple-output (MIMO) multiple-access channels (MAC) and MIMO broadcast channels (BCs) has been established under a total power constraint.

In xDSL systems, in-domain crosstalk is easily dealt with based on zero-forcing receiver or precoding while out of domain or alien crosstalk requires a more advanced processing.

Small cell networks promise to boost the capacity and provide good QoS (Quality of Service) to cell edge users.

Resource Allocation (RA) in cellular networks is a challenging problem due to the demanding user requirements and limited network resources.

In this paper, we study a repeated moral hazard problem in which an agent is paid constant wage every period and retained on the job provided his past performance has met the following standard: he

We introduce new dual-polarization probing codes based on two frequency sweep signals enabling perfect estimation of the tested fiber backscattered optical field.

A time-constrained capital-budgeting problem arises when projects, which can contribute to achieving a desired target state before a specified deadline, arrive sequentially.

The gain of a highly efficient erbium-doped fiber amplifier was measured when pumped at wavelengths between 1.46micron and 1.51micron.

We consider the problem of fair rate allocation and admission control for adaptive video streaming sessions in wireless networks with user dynamics.
