  • COVERT COMMUNICATION FOR COOPERATIVE NOMA WITH TWO PHASES DETECTION 
    Peng, Hongxing; Tian, Zhifa; Li, Xingwang; Wang, Weizheng; Nauryzbayev, Galymzhan; Rabie, Khaled; Gadekallu, Thippa Reddy (Alexandria Engineering Journal, 2022)
    This paper investigates the covert communication of cooperative non-orthogonal multiple access (NOMA) systems, where the near user serves as a decode-and-forward (DF) relay and the far user receives the covert information ...
  • DEVELOPMENT AND THOROUGH INVESTIGATION OF DUAL-BAND WILKINSON POWER DIVIDER FOR ARBITRARY IMPEDANCE ENVIRONMENT 
    Gupta, Rahul; Gabdrakhimov, Bekarys; Dabarov, Aldiyar; Nauryzbayev, Galymzhan; Hashmi, Mohammad (IEEE Open Journal of the Industrial Electronics Society, 2021)
    In the design and development of front-end communication systems, the arbitrary impedance environments are encountered frequently. In this article, a three-port dual-band equal power divider is proposed which also transforms ...
  • FLEXIBLE CARBON CLOTH-BASED SINGLE-ELECTRODE TRIBOELECTRIC NANOGENERATORS WITH INCORPORATED TIO2 NANOPARTICLES 
    Kruchinin, Roman; Nurmakanov, Yerzhan; Nauryzbayev, Galymzhan; Adair, Desmond; Bakenov, Zhumabay; Kalimuldina, Gulnur (Energy Reports, 2022)
    Recently, flexible triboelectric nanogenerators (TENGs) have gained significant interest as a promising autonomous technology for harvesting abundant mechanical energy and powering portable electronic devices. In this ...
  • HARDWARE AND INTERFERENCE LIMITED COOPERATIVE CR-NOMA NETWORKS UNDER IMPERFECT SIC AND CSI 
    Arzykulov, Sultangali; Nauryzbayev, Galymzhan; Celik, Abdulkadir; Eltawil, Ahmed M. (Open Journal of the Communications Society, 2021)
    The conflation of cognitive radio (CR) and non-orthogonal multiple access (NOMA) concepts is a promising approach to fulfill the massive connectivity goals of future networks given the spectrum scarcity. Accordingly, ...
