In this paper, we consider the amplify-and-forward relaying transmission in the downlink of a
multi-channel cellular network with one base station and multiple relay-destination pairs …

We consider a system with a single base station communicating with multiple users over
orthogonal channels while being assisted by multiple relays. Several recent works have …

In this paper, a novel resource allocation algorithm is investigated to maximize the energy
efficiency (EE) in multiuser decode-and-forward (DF) relay interference networks. The EE …

The power allocation problem for multiuser wireless networks is considered under the
assumption of amplify-and-forward cooperative diversity. Specifically, optimal centralized …

In this paper, we consider an amplify-and-forward wireless relay system where multiple
source nodes communicate with their corresponding destination nodes with the help of relay …

The overall performance of a cooperative relaying system largely depends on power
allocation schemes. In this paper, we address the power allocation problem in a network …

We consider a multiuser multirelay network where each source communicates with its
destination via an assigned relay. To ensure fairness among the users, the minimum of the …

We consider a system with a single base station communicating with multiple users over
orthogonal channels while being assisted by multiple relays. Several recent works have …

This paper considers a wireless cooperative cellular data network with a base station and
many subscribers in which the subscribers have the ability to relay information for each other …

In this paper, we consider joint resource allocation of a multicell OFDMA-based networks,
with fixed two-hop decode-and-forward relay stations. A joint cell, channel and power …
