  1. 1. 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

  3. 2. 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.

  4. 3. Reducing Effects of Multipath Propagation With a Blind Equalizer

    University essay from Linköpings universitet/Kommunikationssystem

    Author : Emma Söderström; [2018]
    Keywords : ;

    Abstract : When transmitting data from an aircraft being prepared at the apron (the area in front of the hangar) telemetry data is transmitted to ground personnel. The transmitted data is subject to severe distortion due to multipath propagation created by the surroundings, resulting in erroneous detection. READ MORE

  5. 4. Comparative study of WiMAX and LTE uplink using SDCMA and LSCMA

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Jaswini Reddy Potuganuma; [2010]
    Keywords : Wimax; LTE uplink; physical layer; SDCMA; LSCMA; FSE; blind equalizer;

    Abstract : Blind equalizers are widely used in wireless communications for minimizing Inter Symbol Interference (ISI). The Constant Modulus Algorithm (CMA) is one of the popular blind equalizers used in broad band applications. This master’s thesis investigates the Steepest Descent Constant Modulus Algorithm (SDCMA) i.e. READ MORE

  6. 5. Adaptive filter algorithms for channel equalization

    University essay from Högskolan i Borås/Institutionen Ingenjörshögskolan

    Author : Omprakash Gurrapu; [2009]
    Keywords : ;

    Abstract : Equalization techniques compensate for the time dispersion introduced bycommunication channels and combat the resulting inter-symbol interference (ISI) effect.Given a channel of unknown impulse response, the purpose of an adaptive equalizer is tooperate on the channel output such that the cascade connection of the channel and theequalizer provides an approximation to an ideal transmission medium.
