Design of Physical Layer secure communication for real wireless propagation environment

This research aims to enhance the security of wireless communication. Although significant progress has been made in physical layer secure communication, most of the existing researches are based on theoretical models and do not fully consider the real wireless propagation environment. Therefore, we simulate signal propagation in a complex environment by ray tracing algorithm, comprehensively considering various influencing factors. Experimental results show the effectiveness of the proposed method, which provides a new idea for the design of future physical layer security communication system. This research fills the research gap of the actual environmental factors in the design of secure transmission, and provides a key theoretical basis for improving the performance of communication security.
