    • PURPOSE: A communication device and a relay device are provided to select one of plural relay nodes and receive the signals of plural signal transmission nodes in the selected relay node in order to transmit coded signals after network coding to a signal reception node at one time, thereby increasing the frequency efficiency of a collaborative communication system. CONSTITUTION: A first signal reception unit(511) receives signals from plural signal transmission nodes(531-533), and a selection unit(512) selects one of relay nodes(521-523). A second signal reception unit(515) receives a network-coded signal from a selected relay node, and a decoding unit(516) detects the signals of plural signal transmission nodes after decoding based on the signal received by first and second signal reception units.
    • 目的:提供一种通信设备和中继设备,用于选择多个中继节点中的一个并接收所选择的中继节点中的多个信号传输节点的信号,以便在网络编码之后一次向信号接收节点发送编码信号, 从而提高协作通信系统的频率效率。 构成:第一信号接收部(511)从多个信号发送节点(531-533)接收信号,选择部(512)选择中继节点(521-523)。 第二信号接收单元(515)从所选择的中继节点接收网络编码信号,解码单元(516)根据由第一和第二信号接收单元接收的信号,对解码后的多个信号发送节点的信号进行检测。
