A Physical-network-coding-based amplify and forward cooperation scheme

Amplify and forward is a classical basic user cooperation scheme. In this paper, we propose a Physical-network-coding-based amplify and forward scheme. In time slot 2, users transmit the combinations of the partner's message and their own message through pseudo physical-layer network coding. This is the greater different from the classical scheme, where the user only transmits the partner's bits in cooperation. An outage probability analysis showing the improved performance is carried out, and computer simulations results are shown to agree with the analytical results.
