Distributed space-time code for amplify-and-forward cooperative networks
Cooperative diversity using distributed space-time codes has been recently proposed to form virtual antennas in order to achieve diversity gain. In this paper, we propose a distributed space-time coding with amplify-and-forward relaying. Motivated by protocol (III) presented in, we propose a distributed space-time code for an arbitrary number of relay nodes. The pairwise error probability (PEP) is
