Outage probability of alamouti based cooperative communications with multiple relay nodes using network coding
Gordhan Das Menghwar, Christoph F. Mecklenbräuker · 2010
In this paper, we extend our proposed scheme of cooperative communications based on Alamouti scheme which was aided by a single relay node to forward network coded bits to the destination. In this work, instead of a single relay node, we consider multiple relays forwarding network coded bits, of the information received from the cooperating users, to the destination. With analytical results on the outage probability, we show that the cooperative diversity gain of the proposed scheme increases linearly with m, the number of relay nodes assisting cooperating users by forwarding network coded bits of their information to the destination.
