Abstract:
1. A communication device, comprising: a first signal receiving unit configured to receive signals from a plurality of signal transmission nodes; a selection unit configured to select one relay node from a plurality of relay nodes based on channels between the plurality of signal transmission nodes and the plurality of relay nodes and channels between the plurality of relay nodes and the communication device; the selection unit comprises: a channel information receiving unit configured to receive equivalent channel information from each of the plurality of relay nodes; and a channel information estimation unit configured to estimate channel information of the channel between the plurality of relay nodes and the communication device, wherein the equivalent channel information is estimated when each of the plurality of relay nodes regards the channels between each of the plurality of relay nodes and the plurality of signal transmission nodes as a single channel; a second signal receiving unit configured to receive a network-coded signal from the selected relay node; and a decoding unit configured to perform decoding based on the signals received by the first signal receiving unit and the signal received by the second signal receiving unit, and to detect the signals transmitted by the plurality of signal transmission nodes, wherein the network-coded signal is generated by the selected relay node performing network-coding with respect to the signals received from the plurality of signal transmission nodes.
