BUFFER-BASED TWO-WAY RELAY COMMUNICATION SYSTEM USING LATTICE CODES

摘要

Disclosed is a relay node. An embodiment of the present invention comprises: a receiver for receiving transmission signals which a plurality of source nodes transmit during a first time interval and storing reception signals including the transmission signals; a processor for generating corresponding signals corresponding to the reception signals on the basis of a codeword selected from the lattices of a lattice code, performing lattice decoding on the corresponding signals to generate a relay symbol, and encoding the relay symbol to generate a relay broadcasting signal; and a transmitter for transmitting the relay broadcasting signal to the plurality of source nodes during a second time interval.
