  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).

    Abstract : Channel coding plays a vital role in telecommunication. Low-Density Parity- Check (LDPC) codes are linear error-correcting codes. According to the 3rd Generation Partnership Project (3GPP) TS 38. READ MORE

  4. 3. Comparison of various concatenated convolutional code ensembles under spatial coupling

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

    Author : Gabriel Iro; Rajeshwari Kabbinale; [2017]
    Keywords : Technology and Engineering;

    Abstract : A big challenge faced by the digital communication world today is increasing the reliability of information which is being transmitted. During the transmission of information, there is a possibility that the information is corrupted or distorted. READ MORE

  5. 4. Analysis of the finite length performance of spatially coupled convolutional codes

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

    Author : Ardiana Osmani; Hector Moreno Trujillo; [2015]
    Keywords : Spatial coupling; convolutional codes; braided convolutional codes; parallel concatenated codes; spatially coupled parallel concatenated codes; spatially coupled braided convolutional codes; BCJR algorithm; Technology and Engineering;

    Abstract : Error control coding is an essential part of any well-designed digital communication system. It has been used in structures to protect the information, by enabling reliable delivery of digital data over unreliable communication channels. Even though this is an old topic, enlisted by Shannon in the late 40's, a lot of research is still going on. READ MORE

  6. 5. Construction and Performance Evaluation of QC-LDPC Codes over Finite Fields

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Sohail Noor; Ihsan Ullah; [2010]
    Keywords : Low Density Parity Check LDPC codes; Finite Fields;

    Abstract : Low Density Parity Check (LDPC) codes are one of the block coding techniques that can approach the Shannon’s limit within a fraction of a decibel for high block lengths. In many digital communication systems these codes have strong competitors of turbo codes for error control. READ MORE
