面向无线通信安全的物理层传输技术综述OA

With the rapid development of wireless communication,security has become an increasingly critical concern.Physical layer security techniques have recently attracted significant research interest.This survey presents three representative physical layer transmission techniques:physical layer security,anti-modulation-classification techniques,and radio frequency fingerprint authentication.System performance is evaluated through Monte Carlo simulations,showing that all three techniques significantly enhance communication security and robustness without compromising system performance.A comparative analysis highlights the advantages and limitations of each method,and the survey discusses their potential applications in dynamic,adversarial,and complex electromagnetic environments.
