Abstract :
We consider a cooperative overlay cognitive network, where the secondary exploits the primary retransmissions. We show that by using cooperation, the secondary rate can be considerably increased when compared to other schemes, without causing major impact on the primary performance. The best configuration for the proposed scheme is that in which the secondary nodes are close to the primary transmitter.
