  1. 1. A Study Of Using Communication Signals As Sonar Pulses In Underwater Sensor Systems

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

    Författare :Erica Svensson; [2022]
    Nyckelord :Sonar; Communication signal; Beamforming; Underwater sensor system; WLS estimator; Detection algorithm; Position estimation;

    Sammanfattning : Underwater communication within underwater sensor network is crucial for surveillance of coast and ocean areas. The aim of this report was to examine whether it is realistic to use the communication signal which is sent from one node to another as a sonar pulse, and in such case at what distances. LÄS MER

  3. 2. 5G Positioning using Machine Learning

    Master-uppsats, Linköpings universitet/Reglerteknik

    Författare :Magnus Malmström; [2018]
    Nyckelord :5G; Positioning; Non Line of Sight NLOS ; Urban Canyons; Machine Learning; Neural Networks; Random Forest; Detection; Neyman-Person; Generalized Likelihood Ratio Test; Kalam Filter;

    Sammanfattning : Positioning is recognized as an important feature of fifth generation (\abbrFiveG) cellular networks due to the massive number of commercial use cases that would benefit from access to position information. Radio based positioning has always been a challenging task in urban canyons where buildings block and reflect the radio signal, causing multipath propagation and non-line-of-sight (NLOS) signal conditions.

  4. 3. Implementation and Analysis of Spectrum Sensing Algorithms for SIMO Links

    Master-uppsats, Kommunikationssystem; Tekniska högskolan

    Författare :Techin Eamrurksiri; [2013]
    Nyckelord :cognitive radio; USRP; OFDM; Spectrum sensing; GLRT; SDR;

    Sammanfattning : Cognitive radio is an autonomous transceiver that is continuously sensing theongoing communication in its environment, it then starts the communication whenever it is appropriate. Therefore, cognitive radio helps improving the spectrum utilization of the overall communication system. LÄS MER
