  1. 6. Explaining Neural Networks used for PIM Cancellation

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Fredrik Diffner; [2022]
    Nyckelord :Telecommunication; Passive intermodulation; PIM cancellation; Fully connected neural network; Convolutional neural network; Time series regression; Explainable AI; backpropagation-based XAI methods; perturbation-based XAI methods; Telekommunikation; Passiv intermodulation; PIM-eliminering; Fullt sammankopplade neuronnät; Konvolutionerande neuronnät; Tidsserieregression; Förklarande AI; Bakåtpropagerande-baserade XAI-metoder; Perturbations-baserade XAI-metoder;

    Sammanfattning : Passive Intermodulation is a type of distortion affecting the sensitive receiving signals in a cellular network, which is a growing problem in the telecommunication field. One way to mitigate this problem is through Passive Intermodulation Cancellation, where the predicted noise in a signal is modeled with polynomials. LÄS MER

  3. 7. Methods of self-interference cancellation in full duplex telecommunication systems

    Master-uppsats, Uppsala universitet/Institutionen för elektroteknik

    Författare :Henrik Erlandsson; Viktor Sköldheden; [2021]
    Nyckelord :telecommunication; full duplex; self-interference cancellation; electronics; wireless communication; power amplifier;

    Sammanfattning : With the wireless technology evolving quickly, so does the demand of speed and efficiency. This makes the companies look for new and better ways to improve the current systems. One way of improving the present systems would be to employ Full Duplex Technology. LÄS MER

  4. 8. Extended and Unscented Kalman Filtering for Estimating Friction and Clamping Force in Threaded Fasteners

    Master-uppsats, Uppsala universitet/Signaler och system

    Författare :Mohammad Al-Barghouthi; [2021]
    Nyckelord :Estimation Theory; Extended Kalman Filter; EKF; Unscented Kalman Filter; UKF; Observability; Friction; Clamping Force; Tightening; Torque Controlled; Bolt; Threaded Fasteners;

    Sammanfattning : Threaded fasteners tend to break and loosen when exposed to cyclic loads or potent temperature variations. Additionally, if the joint is held tightly to the structure, distortion will occur under thermal expansion issues. LÄS MER

  5. 9. Implementation of adaptive filtering algorithms for noise cancellation

    Master-uppsats, Högskolan i Gävle/Avdelningen för elektroteknik, matematik och naturvetenskap

    Författare :Tanja Lampl; [2020]
    Nyckelord :;

    Sammanfattning : This paper deals with the implementation and performance evaluation of adaptive filtering algorithms for noise cancellation without reference signal. Noise cancellation is a technique of estimating a desired signal from a noise-corrupted observation. LÄS MER

  7. 10. Acoustic echo cancellation inside a truck cabin

    Master-uppsats, Linköpings universitet/Statistik och maskininlärning

    Författare :Balaji Ramkumar; [2020]
    Nyckelord :Echo Cancellation; NLMS; Normalized Cross Correlation; Truck; Noise;

    Sammanfattning : In the modern world, a day without telecommunication is almost unimaginable. A telecommunication system is used in almost every sector. In earlier days only luxury cars had the feature of a hands free communication but now it has become one of the basic requirements in any segment of vehicles. LÄS MER
