PROBLEM TO BE SOLVED: To provide a multi-user cooperative communication network and method related to transmitting data from multiple source nodes to a destination node, with the assistance of relay nodes. SOLUTION: Source nodes in an IMT (International Mobile Telecommunications)-advanced 4G network transmit data in uplink channels to a relay node and a BS by using a channel code. The relay node decodes independently the data received from each source node, applies network coding to data correctly decoded, and transmits the encoded data to the BS. The BS decodes the encoded data transmitted by the source nodes and the relay nodes cooperatively via a turbo decoding process. The data from each source node are decoded by soft-input soft-output single-user decoders and are decoded, and together with the data from the relay node, they are decoded by a soft-input soft-output multi-user decoder.
