【 摘 要 】

Collaborative communication and physical layer information security are two valuable aspects in the field of modern wireless communication. Combining the characteristics of the two, the physical layer security model based on cooperative communication is studied, and the amplification and forwarding strategy and cooperation among them in this paper, the best security capacity of congestion strategy is analyzed. In the light of the fact that related researches do not involve the analysis of performance scenarios, the comparison of security capacity performance under different scenarios is carried out for amplification forwarding strategy and collaborative congestion strategy. Simulation studies show that the amplification and forwarding strategy is more stable and less susceptible to scenario changes than the cooperative congestion strategy. In addition, the performance improvement caused by the increased number of relay antennas is also equivalent to increasing the number of trunks.
