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. Forward error correction as equalization method

   University essay from

   Author : Jakob Molin; [2019]
   Keywords : ;

   Abstract : The instant demand to achieve high data rate in communication systems is driving the high-speed links into multi Gigabit per second data transitions, where its suffering from inter symbol interference due to bandwidth limitation. Equalizers are used at both the transmitter and receiver side of the link to counteract signal attenuation, reflections, crosstalk and any type of distortion of the signal. READ MORE
