METHOD OF CONTROLLING INTERFERENCE IN MULTI-HOP NETWORK, AND RELAY NODE AND DESTINATION NODE USING THE METHOD OF CONTROLLING INTERFERENCE

摘要

PROBLEM TO BE SOLVED: To provide a method of controlling interference in a multi-hop network based on a MIMO system, capable of more efficiently eliminating an internal interference signal of a node pair and an interference signal between the node pairs, by controlling channel coefficients of relay nodes.SOLUTION: A method of controlling interference of a relay node and between a plurality of node pairs in a multi-hop network according to the present invention includes each of: a step in which the relay node relays signals received from a source node belonging to one node pair among the plurality of node pairs to a destination node pairing with the source node; a step in which the relay node eliminates a part of interference signals between the node pairs by controlling channel coefficients of the relay node; and a step in which the destination node eliminates a residual interference signal among the interference signals using a signal received by the destination node.
