  1. 1. Time synchronization error detection in a radio access network

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Moulika Madana; [2023]
    Keywords : GNSS - Global Navigation Satellite System; OAS - Over-the air-synchronization; PRTC - primary reference time clock; PTP - precision time protocol; Gauss Jordan elimination; GNN- Graph Neural Network; GNSS -Globalt navigationssatellitsystem; OAS - Över-the-air tidssynkronisering; PRTC - Primär referenstidklocka; PTP - Precisionstidprotokoll; Gauss Jordan eliminering; GNN- Graf neurala nätverk;

    Abstract : Time synchronization is a process of ensuring all the time difference between the clocks of network components(like base stations, boundary clocks, grandmasters, etc.) in the mobile network is zero or negligible. It is one of the important factors responsible for ensuring effective communication between two user-equipments in a mobile network. READ MORE

    Keywords : ;

    Abstract : An estimated 450 million people globally do not have access to a fixed or mobile broadband signal. Recently satellite communication companies announced the concept of Megaconstellations which are large networks of inexpensive low Earth-orbiting satellites. These constellations aim to provide internet access across the planet. READ MORE

  4. 3. Development of GNSS Type Processing for the Characterization of the Mobile Propagation Channel

    University essay from KTH/Fastigheter och byggande

    Author : Adrien Bardou; [2021]
    Keywords : LMS Channel; Multi-paths; GNSS; SCHUN; Simulation; LMS-kanal; flerv¨agar; GNSS; SCHUN; Simulering;

    Abstract : Mobile communication systems are undergoing significant development on increasingly wide frequency bands (5G in particular). To support this development, a detailed characterization of the propagation of electromagnetic waves in L, S and C band between a station (satellite, airborne or ground) and a mobile platform is necessary to analyze and model the phenomena that have a decisive impact on the performance, availability and operability of systems.
