  1. 1. Deinterleaving pulse trains with DBSCAN and FART

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för systemteknik

    Författare :Shad Mahmod; [2019]
    Nyckelord :DBSCAN; FART; Fuzzy; Adaptive; Resonance; Theory; Radar; Clustering; Deinterleaving; Machine Learning;

    Sammanfattning : Studying radar pulses and looking for certain patterns is critical in order to assess the threat level of the environment around an antenna. In order to study the electromagnetic pulses emitted from a certain radar, one must first register and identify these pulses. LÄS MER

  3. 3. A Novel and an Efficient Design of an Inverted F-Antenna for Bluetooth Low Energy Communications

    Magister-uppsats, Högskolan i Halmstad/Akademin för informationsteknologi

    Författare :Amer Khatib; [2019]
    Nyckelord :Antenna; Communication; design; testing; Wireless communications; bluetooth.;

    Sammanfattning : Constantly, antenna plays an important role in expanding the wireless communication systems in different technology applications for example, but not limited to, IoT communications and automotive radar systems. On the other hand, the Bluetooth-Low-Energy (BLE) benefits different sorts of applications, as it offers (i) a very low power consumption, (ii) a very fast data transfer, (iii) and an inexpensive/efficient solution as well.

  4. 4. User Equipment Characterization using Machine Learning

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Vanessa Fakhoury; Xin Zhou; [2019]
    Nyckelord :machine learning; characterization; massive MIMO; beamforming; neural networks; support vector machine; logistic regression; multiclass neural networks; Technology and Engineering;

    Sammanfattning : With the ever increasing demand for higher data rates and reliability, efficient management of cellular networks remains a challenge. Among other technologies, fifth generation systems are expected to tackle this challenge using large electronically controllable antenna arrays operating in the time division duplex mode. LÄS MER

  5. 5. Design of a UAV-based radio receiver for avalanche beacon detection using software defined radio and signal processing

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Signaler och System

    Författare :Richard Hedlund; [2019]
    Nyckelord :Signal processing; Software Defined Radio; Avalanche; Beacon; Antenna; SDR; DSP; Signalbehandling; Mjuvarudefinierad Radio; Lavin; Lavinsändare; Antenn; SDR; DSP;

    Sammanfattning : A fully functional proof of concept radio receiver for detecting avalanche beacons atthe frequency 457 kHz was constructed in the work of this master thesis. The radioreceiver is intended to be mounted on an unmanned aerial vehicle (UAV or drone)and used to aid the mountain rescue teams by reducing the rescue time in findingavalanche victims carrying a transmitting beacon.
