In this paper, we consider the joint optimization of the source power allocation and relay
beamforming weights in distributed multiuser peer-to-peer (MUP2P) relay networks applying …

Equal allocation of bandwidth and/or power may not be efficient for wireless multi-user
networks with limited bandwidth and power resources. Optimal joint bandwidth and power …

In this paper, we consider the adaptive subcarrier assignment and fair power control strategy
that minimize a cost function of average relay powers for multiuser wireless orthogonal …

In energy-constrained wireless networks such as sensor networks, it is important to
maximize power efficiency by minimizing power consumption for a given quality of service …

In this paper, altruistic coalition formation in cooperative relay networks is studied. The
communication is performed over two phases, the broadcasting phase and the cooperation …

Massive multiple-input multiple-output (MIMO) is still valid as an important system to
increase performance of fifth generation (5G) and beyond wireless communication …

In this paper, we address the problems of power allocation at relays to maximize the
transmission rate in a nonorthogonal amplify-and-forward (AF) relay-assisted network, in …

This paper considers the joint power-allocation and relay-selection problems in multiuser
cooperative communication networks, where one user can only seek a limited number of …

In this paper, multi-user relay networks are considered. We formulate a multi-user relay
network model where all the relay nodes amplify and forward the signals from the source …

A wireless relay network with one source, one relay and one destination is considered,
where nodes communicate via N orthogonal channels. We develop optimal power allocation …
