    Design scheme of physical layer security for intelligent reflecting surface-assisted MISO communication system by Xiaorong JING, Zhenyuan SONG, Wei GAO, Weijia LEI, Qianbin CHEN

    Published 2022-01-01
    “…Intelligent reflecting surface (IRS) improves the physical layer security of the communication systems by adjusting the phases of the reflecting units.A scheme of physical layer security design based on alternative iteration was proposed for IRS-assisted multiple input single output (MISO) communication system.Firstly, aiming at maximizing the secrecy rate, a non-convex objective function with non-convex constraints was constructed.Secondly, the Dinkelbach algorithm and Riemannian manifold optimization algorithm were adopted to transform the non-convex problem into a series of solvable sub-problems.Finally, the alternate iteration method was used to achieve the optimization design of transmit beamforming and IRS phase shift matrix.The simulation results show that, compared with the several existing schemes, the proposed scheme can achieve a better tradeoff between computational complexity and system security rate.…”

    English communicative competence and predominant language for online use through smartphones in Croatia as compared to Slovenia by Varga Mirna, Jurkovič Violeta, Sierocka Halina

    Published 2018-12-01
    “…The study explores which languages are predominant in the online use among the targeted participant population in Croatia and Slovenia and examines the association between the participants’ smartphone online use of English and preferred subtitling mode with their perceived communicative competence in English. The findings indicate that in both nationality groups the use of English prevails in receptive language activities, in particular listening and audio-visual reception, while mother tongues are mainly used for productive and interactive activities. …”
