Embodiment Construction
[0037] The present invention will be further described below with reference to the accompanying drawings.
[0038] refer to figure 1 , the method of the present invention is in figure 1 realized in the scenario. exist figure 1 Among them, the source node and the destination node are equipped with one antenna, and the relay node is equipped with two antennas. The source node uses half-duplex mode to transmit signals, the destination node uses half-duplex mode to receive signals, and the relay node uses full-duplex mode. Receive and send signals. figure 1 f in represents the channel parameters from the source node to the relay node, figure 1 h in represents the relay node loop channel parameter, figure 1 The g in represents the channel parameter from the relay node to the destination node. The source node sends a signal to the relay node in each time slot, and the relay node uses amplification and forwarding to amplify and forward the received signal, and the destination nod...
