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

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för system- och rymdteknik

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

    Sammanfattning : 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. LÄS MER

  3. 2. Blind Channel Equalization for Shortwave Digital Radio Communications

    Master-uppsats, Linköpings universitet/Reglerteknik

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

    Sammanfattning : 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.

  4. 3. Modulation Domain Improved Adaptive Gain Equalizer for Single Channel Speech Enhancement

    Master-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Författare :Nettem.Adithyavalli ; Shakira Shaheen; [2013]
    Nyckelord :Speech Enhancement; Adaptive Gain Equalizer; Improved Adaptive Gain Equalizer;

    Sammanfattning : Human speech is the main method for personal communication. During communication speech may get impaired with ubiquitous noise. Enduring interfering noise decreases speech intelligibility and makes speech communication troublesome. LÄS MER

  5. 4. Eye opening monitor for optimized self-adaptation of low-power equalizers in multi-gigabit serial links

    Master-uppsats, Linköpings universitet/Elektroniksystem; Linköpings universitet/Tekniska högskolan

    Författare :Anand Narayanan; [2013]
    Nyckelord :Inter-symbol interference; Adaptive Equalizer; Eye opening monitor; Receiver; Continuous time linear equalizer;

    Sammanfattning : In modern day communication systems, there is a constant demand for increase in transmission rates. This is however limited by the bandwidth limitation of the channel. Inter symbol interference (ISI) imposes a great threat to increasing data rates by degrading the signal quality. LÄS MER

  7. 5. Simulation of wireless communications in underground tunnels

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

    Författare :Shabai He; [2012]
    Nyckelord :time dispersion channels; intersymbol interference; adaptive equalization;

    Sammanfattning : The new released 4G standard wireless communication reminds us that higher transmission data rate and more reliable service are required urgently. However, to fulfill the demand can face problems in a complex environment like mines. LÄS MER
