APPARATUS AND METHOD FOR BI-DIRECTIONAL COMMUNICATION BETWEEN MULTI PAIR NODES USING RELAY NODE

摘要

PURPOSE: A two-way communication apparatus between multi-nodes using a relay node is provided to encode signals by estimating lattice code total signals between a plurality of user nodes and a base station. CONSTITUTION: A reception unit(410) receives signals encoded using a nested lattice code chain from a base station and one or more nodes. A decoding unit(420) estimates M lattice code total signals which make a pair between the base station and the nodes based on the nested lattice code chain for the encoded M signals. A transmission unit(430) transmits the M lattice code total signals to the base station and the M user nodes when the set time is over.
