연구 분야: Infrastructure

학회: 2023 IEEE International Symposium on Broadband Multimedia Systems and Broadcasting (BMSB)

As an emerging technology for simultaneous co-frequency transmission, full-duplex technology can theoretically multiply the spectral efficiency, and with the improvement of self-interference elimination ability, full-duplex technology shows great potential in improving the security and reliability of future mobile communication systems. The broadcast and openness of wireless channels make information easy to eavesdrop, and how ensure the safe transmission of explosive growth data has brought severe challenges to wireless communication technology. As a supplement to the upper-layer security technology, the physical layer security technology can be effectively compatible with the existing technology and improve the security of legal links from the perspective of information theory. This paper focuses on the physical layer security technology of full-duplex trunk systems.
