A relay node is disclosed. According to an embodiment, the relay node comprises: a receiver for receiving transmitting signals which transmitting source nodes have transmitted during a first time interval and storing a receiving signal having the transmitting signals in a buffer; a processor for generating a corresponding signal corresponding to the receiving signal based on a code word selected from a lattice of a lattice code, generating a relay symbol by lattice-decoding the corresponding signal, and generating a relay broadcast signal by encoding the relay symbol; and a transmitter for transmitting the relay broadcast signal to the source nodes during a second time interval, thereby obtaining a higher performance than an existing bidirectional relay communication system. |
