• Selektywne zakłócanie transmisji OFDM w interfejsie radiowym NB-IoT

  Publikacja

  • J. Magiera

  - Przegląd Telekomunikacyjny + Wiadomości Telekomunikacyjne - Rok 2023

  W artykule przedstawiono zagadnienie tzw. inteligentnego zagłuszania, polegającego na selektywnym zakłócaniu krytycznych składowych sygnału OFDM. Opisane zostały badania weryfikujące możliwość przeprowadzenia tego rodzaju ataku elektronicznego. Przedstawiono zrealizowane stanowisko badawcze, umożliwiające zakłócanie rzeczywistych sygnałów NB-IoT w łączu w dół. Wyniki badań wykazują możliwość realizacji selektywnego zagłuszania...

• A Simplistic Downlink Channel Estimation Method for NB-IoT

  Publikacja

  • J. Magiera

  - Applied Sciences-Basel - Rok 2023

  This paper presents a downlink channel estimation method intended for a Narrowband Internet of Things (NB-IoT) access link. Due to its low computational complexity, this method is well suited for energy-efficient IoT devices, still providing acceptable reception quality in terms of signal-to-noise (SNR) performance. This paper describes the physical layer of NB-IoT within the scope of channel estimation, and also reviews existing...
