We consider various relaying strategies for wireless networks by comparatively examining
direct transmission, conventional relaying, and the novel concepts of cooperative relaying …

Cooperative relaying recently emerged as a viable option for future wireless networks. By
simultaneously exploiting path loss savings known from relaying scenarios and the diversity …

In this paper, we propose and analyze a simple protocol that simultaneously exploits two
potentials offered by wireless relay systems: diversity gains and pathloss savings. An …

We propose a novel half-duplex decode-and-forward relaying scheme based on partial
repetition coding at the relay. In the proposed scheme, if the relay decodes the received …

In this paper; we propose a new cooperative communication protocol, which achieves
higher bandwidth efficiency while guaranteeing the same diversity order as that of the …

Cooperative communication has the potential of providing better throughput and reliability to
wireless systems when compared with direct communication. To realise the potential gain, it …

Cooperative transmission protocols over fading channels are based on a number of relaying
nodes to form virtual multi-antenna transmissions. Diversity provided by these techniques …

In recent years, a new paradigm for communication called cooperative communications has
been proposed for which initial information theoretic studies have shown the potential for …

Cooperative communication is capable of forming a virtual antenna array for each node
(user) in a network by allowing the nodes (users) to relay the messages of others to the …

This paper provides a general analysis of cooperative amplify-and-forward relay networks
and gives a unified and comparative view of various proposed systems. The studied …
