METHOD OF BINARY CODED PHYSICAL-LAYER NETWORK CODING

摘要

PURPOSE: A physical layer network coding method which uses a binary code is provided to reduce the loss of an achievement rate compared to a physical layer network coding method using a non-binary code or lattice code, thereby significantly reducing computational complexity. CONSTITUTION: A first and second source nodes(N1,N2,11,12) perform wireless communication using a physical layer network coding method through relay nodes(N3,13). Source nodes are corresponding to a base station or a terminal as a source node which is mutually exchanging information. The relay node interprets the information between the first and second source nodes. An information bit of each source node is encoded by a binary encoding part. The relay node decodes a signal received from the first and second source nodes. The information bit decoded in the relay node is binary-encoded again.
