METHOD FOR COOPERATIVE COMMUNICATION USED RELAY NODE IN COOPERATIVE COMMUNICATION NETWORK

摘要

PURPOSE: A cooperative communication method using a relay node in a cooperative communication network is provided to maximize a channel capacity by selecting a relay node and changing the order of relay nodes in a unidirectional cooperative communication network. CONSTITUTION: A channel capacity between the source node and the destination node is calculated using transmission power about a channel set between a source node and a relay node and transmission power for a channel set between the relay node and a destination node. A relay node for signal transmission is selected by comparing the calculated channel capacities according to each relay node.
