Semantic security for indoor THz-wireless communication

, 2022
S.418-423Physical-layer security (PLS) for industrial indoor terahertz (THz) wireless communication applications is considered. We use a similar model as being employed for additive white Gaussian noise (AWGN) wireless communication channels.
