An adaptive regenerate and forward cooperative diversity (CD) system using quadrature amplitude modulation (QAM) for a two-user cooperation is proposed. The proposed system can ach...
In this paper, we consider a secondary link sharing the spectrum with a primary link in a fading cognitive radio (CR) network. Instead of applying the conventional interference pow...

Power allocation strategies are devised to maximize the network lifetime of amplify-and-forward (AF) cooperative networks in this work. We consider the scenario where one source an...
Abstract— Discrete power allocation strategies for amplifyand-forward cooperative networks are proposed based on selective relaying methods. The goal of power allocation is to ma...
— In this paper, we study how to appropriately match users for two-user cooperative diversity systems that deploy optimal power allocation for an amplify and forward or a regener...

Abstract—The throughput of multi-hop communication systems can significantly be increased by the application of MIMO concepts. To utilize the physical resources in an efficient...
