    Noise resistance of remote authentication via LTE network
    (Information and Telecommunication Sciences, 2020) Astrakhantsev, A.; Liashenko, G.; Shcherbak, A.
    Background. LTE networks support a wide range of applications and services. These networks provide high-quality mobile services and have increased transmission rates and often used for remote biometric authentication, but the influence of noise and fading in wireless channels on quality and stability of biometric authentication is not analyzed yet. Objective. The aim of the paper is to study the model of the physical layer of the LTE network, which transmits biometric templates for authentication. Methods. We use computer simulation of biometric authentication system for preparing biometric template and Matlab models of wireless communication channel using the LTE technology for analysis of influence of noise and fading on channel. Results. The paper presents the results of the evaluation of the authentication system under the influence of interference in communication channels. The impact of the use of MIMO technology on the dependence of the number of bit errors is evaluated. The obtained results show that in order to improve the quality of remote biometric authentication systems, it is advisable to use additional means of noise immunity and the use of adaptive settings on the transmitter side. Conclusions. The system of remote biometric authentication with data transmission via LTE network was modeled. Influence of AWGS and Doppler shifts in wireless communication channels was analyzed. For noise resistance different error correction codes are implemented.
