  1. 1. 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.

  5. 4. Visualizing future buildings : User-centered design process and evaluation of a sensor-based MAR prototype

    University essay from KTH/Skolan för datavetenskap och kommunikation (CSC)

    Author : Daniel Lindström; [2017]
    Keywords : Mobile Augmented Reality; MAR; Sensor-based MAR; User-Centered Design; UCD; Human-Computer Interaction; HCI;

    Abstract : Mobile Augmented Reality (MAR) is an emerging technology that, when done right, can offer the users a rich experience. However, as with most emerging technologies, it is primarily technology-driven, often leaving the user needs aside. In this study a sensor-based MAR prototype was developed and evaluated, following a User-Centered Design process. READ MORE

  6. 5. An approach to automating mobile application testing on Symbian Smartphones : Functional testing through log file analysis of test cases developed from use cases
