Cooperative device-to-device (D2D) wireless systems use relays such as amplify-and-forward (AaF) and decode-and-forward (DaF). The AaF relay is simple to implement but amplifies noise as well. Conventional DaF relay does decoding and acts as a regenerative relay, hence deliver better noise performan...
