Abstract: A two-way wireless relay transmission method suitable for multiple relay nodes proposes a transmission solution based on a Decode-and-Forward (DF) technology and Network Coding (Network Coding, NC) technology suitable for a two-way wireless relay network. The method has an advantage of achieving a maximum spectrum efficiency based on the DF technology, and proposes a retransmission-free error control solution to avoid a problem of error spreading brought about by the NC technology to obtain an effective transmission throughput that is superior to existing solutions.
