Embodiment Construction
[0066] The system model studied by the present invention is based on the two-way relay channel model (TWRC, Two-WayRelay Channel) of literature [4] and has added two elements of internal and external eavesdroppers simultaneously, making the applicability of the model stronger, two-way A relay channel model such as figure 1 Shown, the system model of the present invention is as figure 2 As shown, the legal communication parties are the source nodes A and B. Since A and B are far away and cannot directly receive the information sent by the other party, a relay R needs to be added between A and B. R uses ANC. In addition, R has another identity—an internal eavesdropper, and the model also considers an external eavesdropper E. CJ type implements interference for source A. Each node is equipped with an omnidirectional antenna, and the channel is half-duplex, so the sending and receiving of a node must occur in different time slots.
