Abstract
In this paper, we propose a distributed space-time coded cooperative protocol with amplify-and-forward relaying. Motivated by protocol (III) presented in , we propose a distributed space-time coding for an arbitrary number of relay nodes. The pairwise error probability (PEP) is derived and the theory analysis demonstrates that our protocol achieves a diversity of order N +1 where N is the number of relay nodes. Quasi-orthogonal space-time codes are used as they give much better performance than random linear-dispersion codes. As the transmission power of the source node is a critical parameter in this protocol because it transmits in both phases, the optimal power allocation is derived using numerical and theoretical analysis.
