METHOD OF CONTROLLING INTERFERENCE IN A MULTI-HOP NETWORK BASED ON MIMO SYSTEM AND A RELAY NODE AND NODE PAIR ENABLING THE METHOD

摘要

Disclosed are a method of controlling interference in a multi-hop network based on a MIMO system and a relay node and a node pair using the method. A method of controlling interference of relay nodes and node pairs in the multi-hop network, includes: relaying signals received from source nodes among the node pairs to destination nodes pairing with the source nodes; and cancelling a part of interference signals between two or more of the node pairs by controlling channel coefficients of the relay nodes. The node pairs are configured to cancel residual interference signals among the interference signals between the two or more of the node pairs, using the signals received by the destination nodes.
