  1. 1. On the statistics and practical application of the reassignment method for Gabor spectrograms

    University essay from Lunds universitet/Matematisk statistik

    Author : Erik. M Månsson; [2019]
    Keywords : Mathematics and Statistics;

    Abstract : The reassignment method is a technique for improving the concentration of signals in spectrograms and other time-frequency representations (TFR). It achieves this by displacing the points in a TFR according to the reassignment vector for every point. READ MORE

  2. 2. Cascade Matched Filtering & Adaptive Threshold Techniques on Optical Tracking Signals under AWGN

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Sebastian Elm; [2019]
    Keywords : Technology and Engineering;

    Abstract : A cascade matched filtering (CMF) approach is purposed for filtering rectangular pulse train tracking signals, with known signal characteristics, in an embedded signal detection unit. Two adaptive detection algorithms are suggested, adapting to alterations in noise signal characteristics, due to environmental changes. READ MORE

  3. 3. Symmetric alpha-Stable Adapted Demodulation and Parameter Estimation

    University essay from Luleå tekniska universitet/Signaler och system

    Author : Kristoffer Hägglund; [2018]
    Keywords : ;

    Abstract : Transmission and reception of signals in wireless communication systems is affected by additive interference corrupting the signal. Traditionally, the interference is assumed to be AWGN and the system designs are usually based on that assumption. READ MORE

  4. 4. A comparison of Polar Code Constructions and Punctur-ing methods for AWGN and Fading channels

    University essay from KTH/Teknisk informationsvetenskap

    Author : Jonas Sedin; [2017]
    Keywords : ;

    Abstract : Today 5G and other wireless standards are being developed for the future of our society. The different use-cases of future wireless services are going to be ever-more demanding, whether it is vehicular communication or low-powered sensor networks. READ MORE

  5. 5. Statistical Analysis of Equalization Enhanced Phase Noise in Coherent Fiber Optical Communications

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : Thomas Gaudy; [2016]
    Keywords : ;

    Abstract : Coherent optical communications increase the receiver sensitivity and the total capacity. Together with high speed digital signal processing (DSP), compensation for linear transmission impairments (chromatic dispersion, polarization mode dispersion and phase noise) can be achieved.
