  1. 1. Control system and simplified timesynchronization for heterogenous IoT systems with medium time requirements

    University essay from KTH/Hälsoinformatik och logistik

    Author : Jemma Touma; Simon Hejdenberg; [2024]
    Keywords : Internet of Things; time synchronization; wireless sensor networks; network time protocol; Android; Bluetooth; WiFi Direct;

    Abstract : The company QTPIE conducts research on drivers and their unconscious reactions when driving. To help, they use smart devices that today must be individually handled at the start and end of a run, and have individually set timestamps, which can lead to differences between the units when data is entered and collation of the units' data after a run.

  3. 2. Comparative Analysis and Development of Receivers for Drone Remote Identification

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

    Author : Xiaolinglong Guo; [2023]
    Keywords : drone detection; remote identification; field test; wireless receiver; drönardetektering; fjärridentifiering; fälttest; trådlös mottagare;

    Abstract : Similar to a car’s license plate, the European Union Aviation Safety Agency (EASA) has released new regulations imposing the registration of drone operators and the broadcasting of the drone’s “digital license plate”, i.e., the drone Remote Identification (RID) in flight, which gives a new opportunity in drone surveillance.

  4. 3. Adaptive Modulation Coding Scheme in Amplify and Forward Relay Networks

    University essay from Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Author : Nirnay Reddy Nallavelli; Sushma Swaraj Chilupuri; [2022]
    Keywords : Adaptive Modulation; Modulation and Coding Schemes; Amplify and Forward; Signal to Noise Ratio; Nakagami-m Distribution.;

    Abstract : Wireless communications have become an essential part of our daily life. Despite the fact that wireless networks are simple to set up and deploy, the channel conditionsin wireless networks are susceptible to fading and attenuation, thereby reducing the transmission efficiency and reliability.

  5. 4. Far-field pattern synthesis of transmitarray antennas using convex optimization techniques

    University essay from KTH/Tillämpad fysik

    Author : Marie Defives; [2022]
    Keywords : Applied physics; Transmitarray antennas; convex optimization; Tillämpad fysik; Transmitarray-antenner; konvex optimering;

    Abstract : Transmitarrays antennas (TAs) can be seen as the planar counterpart of optical lenses. They are composed of thin radiating elements (unit cells) which introduce different local phase shifts on an incident electromagnetic wave, emitted by a primary source, and re-radiate it. READ MORE

  6. 5. Decode and Forward Relay Assisting Active Jamming in NOMA System

    University essay from Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Author : Lakshmikanth Akurathi; Surya Teja Reddy Chilluguri; [2022]
    Keywords : Physical Layer Security; Power-domain NOMA; Decode and Forward Relay; Jamming in NOMA; Nakagami-m Fading; Relay Transmission; Secrecy Performance.;

    Abstract : Non-orthogonal multiple access (NOMA), with its exceptional spectrum efficiency, was thought to be a promising technology for upcoming wireless communications. Physical layer security has also been investigated to improve the security performance of the system. READ MORE
