Amplify-and-forward with partial relay selection

IEEE Communications Letters, 2008
This letter offers a statistical analysis of the basic two-hop Amplify-and-Forward link, where the relay node is selected based on instantaneous and partial knowledge of the channel. In contrast with previously reported work, where relay selection requires global knowledge (2 hops) of the relaying link, the problem considered is interesting in ...

Scheduling for Amplify-and-Forward Cooperative Networks

IEEE Transactions on Vehicular Technology, 2007
We consider a basic cooperative network that is composed of three nodes which use Amplify-and-Forward as a cooperative strategy. This simple setup assumes that each time, one node is the source, one node is the relay, and one node is the destination.

Adaptive Amplify-and-Forward Cooperative Channel

2007 IEEE International Symposium on Information Theory, 2007
In this work, we propose an amplify-and- forward (AF) protocol based on a new selection criterion, a function of the instantaneous capacities of all possible transmission schemes (with or without cooperation). The outage probability and the simulation results show that the new Adaptive AF protocol has better performance than the best known AF protocol (
