  1. 1. Faster than Nyquist Signaling with Spatial Coupling

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Haoran Liu; Lingwei Zhang; [2022]
    Keywords : Technology and Engineering;

    Abstract : The emergence of the Faster-Than-Nyquist signaling (FTN) technology has im- proved the tight spectrum resources by compressing the transmission interval between adjacent pulses. In a natural environment, data transmission via a wire- less medium and through multi-path, at a high data rate, the leakage of these paths among symbols can cause severe inter-symbol interference (ISI).

  3. 2. A Blind Constellation Agnostic VAE Channel Equalizer and Non Data-Assisted Synchronization

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Fredrik Reinholdsen; [2021]
    Keywords : Blind; Equalization; Machine Learning; Variational; Autoencoder; VAE; Constellation; Agnostic; Synchronization; Neural; Networks;

    Abstract : High performance and high bandwidth wireless digital communication underlies much of modern society. Due to its high value to society, new and improved digital communication technologies, allowing even higher speeds, better coverage, and lower latency are constantly being developed. READ MORE

  4. 3. Channel Equalization Using Machine Learning for Underwater Acoustic Communications

    University essay from Linköpings universitet/Kommunikationssystem

    Author : Martin Allander; [2020]
    Keywords : underwater; communications; channel estimation; channel equalization; machine learning;

    Abstract : Wireless underwater acoustic (UWA) communications is a developing field with various applications. The underwater acoustic communication channel is very special and its behavior is environment-dependent. The UWA channel is characterized by low available bandwidth, and severe motion-introduced Doppler effect compared to wireless radio communication. READ MORE

  5. 4. Blind Channel Equalization for Shortwave Digital Radio Communications

    University essay from Linköpings universitet/Reglerteknik

    Author : Tomas Busk; [2020]
    Keywords : Blind Channel Equalization; Equalization; adaptive filter; radio communication; Blind kanalutjämning; kanalutjämning; adaptivt filter; radiokommunikation;

    Abstract : In this thesis the concept of Blind Channel Equalization has been examined and algorithms suitable to blindly equalize the channel are presented and evaluated on simulated data. The concept of blind equalization is to equalize a communica- tions channel without relying on a training sequence or pilot tone, which may be either unknown to the receiver or not exist at all.

  6. 5. Optimized Training Signal Design

    University essay from KTH/Signalbehandling

    Author : Marie Maros; [2014]
    Keywords : ;

    Abstract : In this thesis, the problem of finding an optimal training sequence for estimating a MIMO flat fading channel with spatially and temporally correlated Gaussian noise is considered. The methods analyzed tailor the training sequence not only according to the known statistical CSI but also to the specific purpose the channel estimate will fulfill. READ MORE
