Physical Layer Network Coding for the K-User Multiple Access Relay Channel

A Physical layer Network Coding (PNC) scheme is proposed for the K-user wireless Multiple Access Relay Channel (MARC), in which K source nodes transmit their messages to the destination node D with the help of a relay node R: The proposed PNC scheme involves two transmission phases: Phase 1 during which the source nodes transmit, the relay node and the destination node receive and Phase 2 during which the source nodes and the relay node transmit, and the destination node receives. At the end of Phase 1, the relay node decodes the messages of the source nodes and during Phase 2 transmits a many-to-one function of the decoded messages.
