Abstract :
Cooperative network with the amplify-and-forward (AF) protocol is attractive for its simplicity and nonloss of soft information. In this paper, we analyze relay region where cooperative transmission with the AF protocol outperforms direct transmission. In high SNR regimes, we derive an analytical expression of the relay region, and propose a geometric explanation for uncoded binary phase shift keying (BPSK) modulation. Simulation results confirm our theoretical analysis.
