  1. 1. Utilizing Neural Networks To Adaptively Demodulate And Decode Signals In An Impulsive Environment

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

    Författare :Andreas Andersson; [2023]
    Nyckelord :Neural Network; Demodulation; Decoding; Impulsive Noise; Alpha-stable Noise;

    Sammanfattning : Electromagnetic disturbance can be detrimental to the performance of a radio communication system, and in today’s society where more and more electronic devices are present in our everyday life it is increasingly vital to consider man-made interference. A communication system can take into consideration the noise characteristics and by doing so will excel in such areas, however, this follows that the algorithms utilized in such systems are more computationally complex and are therefore slow.

    Sammanfattning : This bachelor's thesis aims to implement a wave propagation experiment on Field-Programmable Gate Array to detect the signal strength at pre-defined frequencies for use in sounding rocket experiments. This includes the choice of suitable components such as analog to digital converters, filters, voltage regulators, and amplifiers. LÄS MER

  5. 4. Image Synthesis Using CycleGAN to Augment Imbalanced Data for Multi-class Weather Classification

    Master-uppsats, Linköpings universitet/Medie- och Informationsteknik; Linköpings universitet/Tekniska fakulteten

    Författare :Marcus Gladh; Daniel Sahlin; [2021]
    Nyckelord :;

    Sammanfattning : In the last decade, convolutional neural networks have been used to a large extent for image classification and recognition tasks in a number of fields. For image weather classification, data can be both sparse and unevenly distributed amongst labels in the training set. LÄS MER
