Abstract :
The first opportunistic cooperative communications scheme based upon nonorthogonal transmission, namely the opportunistic nonorthogonal amplify-and-forward scheme, is proposed. It is proved that the proposed scheme can achieve a superior diversity- multiplexing trade-off performance bound than the existing opportunistic relaying schemes. Simulation results validate the proof.
