Embodiment Construction
[0060] The present invention will be further described below in conjunction with embodiment and accompanying drawing.
[0061] The system model aimed at by the full-duplex cognitive MIMO relay cooperation method in the non-ideal channel state of the present invention is a full-duplex cognitive wiretapping system under the full-duplex working mode of the secondary user destination node, such as figure 1 As shown, the system includes a secondary user transmitter (Alice), a secondary user relay node (Relay), a full-duplex destination node (Bob), an eavesdropping user (Eve) and a primary user (PU), where the secondary user transmitter (Alice) Configure N A (N A >1) root antenna, secondary user relay node (Relay) configuration N R (N R >1) Antenna, full-duplex destination node (Bob) configuration NB (N B >1) One antenna, the eavesdropping user (Eve) and the primary user (PU) are both configured with at least one antenna, and in the embodiment of the present invention, the eaves...
