METHOD FOR OPTIMUM RELAY SELECTION IN BIDIRECTIONAL COOPERATIVE DIVERSITY NETWORKS

摘要

PURPOSE: A method for selecting an optimal delivery terminal in a bidirectional cooperative communication network is provided to select a delivery terminal which minimizes an outage probability in the bidirectional cooperative communication network including two source terminals and the delivery terminal. CONSTITUTION: Relay node adding-up receiving power which is the sum of first relay receiving power for a first signal and second relay receiving power for a second signal is calculated. A first via signal-to-noise ratio for a first signal passing via a relay node(R) and a second via signal-to-noise ratio for a second signal passing via the relay node are calculated by using the first relay receiving power and the second relay receiving power. The channel capacity of each relay node is calculated by using a signal-to-noise ratio, the first via signal-to-noise ratio, and the second via signal-to-noise ratio. The outage probability of each relay node is calculated by using the channel capacity.
