TL;DR: Simulation and analysis show that the proposed scheme actually can achieve a secure and precise wireless transmission of confidential messages in line-of-propagation channel, and the derived theoretical formula of average secrecy rate is verified to coincide with the exact results well for medium and large scale transmit antenna array or in the low and medium SNR regions.

TL;DR: In this article, evaluating the IoT platforms is formulated to be a multicriteria decision-making (MCDM) problem since it involves multiple considerations and a novel integrated MCDM method is put forward for handling this problem.

TL;DR: Simulation results show that compared with conventional methods, the proposed robust scheme achieves much better bit error rate performance along desired directions for a given signal-to-noise ratio (SNR).

TL;DR: The key challenging problems for achieving physical layer security in URLLC are identified, the role that channel state information can have in providing potential solutions to these problems are discussed, and recommendations on future research directions in this emerging area are presented.

TL;DR: In this paper, some novel directional correlation coefficients are put forward to compute the relationship between two Pythagorean fuzzy sets by taking four parameters of the PFSs into consideration, which are the membership degree, non-membership degree, strength of commitment, and direction of commitment.
