  1. 11. Measurements, Estimations and Calibration with a Fully Digital Array

    University essay from Uppsala universitet/Signaler och system

    Author : Oscar Magnér; [2023]
    Keywords : WiDAR; signal processing; digital array; broadband antenna; array antenna; antenna; calibration; direct sampling; antenn; bredbandig; digital array; array antenn; direktsampling; signalbehandling; kalibrering; WiDAR; Saab AB; SAAB;

    Abstract : In modern digital communication, transmission and reception of information through electromagnetic signals requires digital devices that can process high data rates accurately despite being located in information heavy environments. One type of antenna receiver is the digital antenna array, which can steer its lobes electronically to increase or decrease sensitivity in specific directions. READ MORE

  3. 12. Evaluating GPU for Radio Algorithms : Assessing Performance and Power Consumption of GPUs in Wireless Radio Communication Systems

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

    Author : Albin André; [2023]
    Keywords : GPU; CUDA; Signal Processing; Radio; Algorithms; GPU; CUDA; Signalbehandling; Radio; Algoritmer;

    Abstract : This thesis evaluates the viability of a Graphics Processing Unit (GPU) in tasks of signal processing associated with radio base stations in cellular networks. The development of Application Specific Integrated Circuits (ASICs) is lengthy and highly expensive, but they are efficient in terms of power consumption. READ MORE

  4. 13. 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.

  5. 14. Characterisation of the LYCCA Double-Sided Silicon Strip Detectors

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Partikel- och kärnfysik

    Author : Marwan Mohamed; [2023]
    Keywords : DSSD LYCCA HISPEC FAIR Characterisation; Physics and Astronomy;

    Abstract : The goal of this thesis work is to describe the methods used and perform comprehensive testing of the Double-Sided Silicon-Strip Detectors (DSSD) prior to their implementation in the Lund-York-Cologne CAlorimeter (LYCCA) detector. In the framework of this project, the DSSD characterisation was carried out to ensure specification compliance prior to their "in-kind contribution" delivery to the HISPEC experiment at the NUSTAR collaboration.
