Opportunistic cooperation is a technique where in each transmission the best relay (or k best relays) are chosen to assist. In a multiuser cooperative network, coordinating the cooperating users requires exchange of channel information between various nodes. As the number of nodes increases, this information exchange can get out of hand. In this work, we propose an opportunistic cooperation technique where at most two bits of information per relay are exchanged for each cooperation period (one… CONTINUE READING
