Joint optimization method for full-duplex destination scrambling secure transmission

Abstract

The invention provides a joint optimization method for full-duplex destination end scrambling safe transmission, which comprises the following steps: step S1, constructing a wireless communication system comprising a source node, an eavesdropping node and a full-duplex destination end node; step S2, sending a source signal to the eavesdropping node and the full-duplex destination node by the source node, and sending an interference signal to the eavesdropping node by the full-duplex destination node; Step S3, calculating the first SINR value of the source signal received by the full duplex destination node, calculating the second SINR value of the source signal and the interference signal received by the eavesdropping node, and counting the channel parameters; 4, using the first SINR value, the second SINR value and the channel parameters to respectively solve the safety rate, the optimal power allocation and the optimal allocation scheme of the full-duplex destination node antenna. The invention has the advantages that the antenna freedom degree is fully utilized, the material is fully utilized, the power is reasonably distributed, and the resource waste is avoided.

In the traditional scrambling scheme, the antenna adopts a fixed working mode

This solution has the following defects: 1. Since the working mode of all antennas is fixed as receiving mode or transmitting mode, the utilization rate and play space of the antenna are greatly limited; 2. Since the scrambling scheme does not apply the optimal power allocation scheme, Make the power utilization of the system low
