  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. Implementation and optimization of LDPC decoding algorithms tailored for Nvidia GPUs in 5G

    University essay from Karlstads universitet/Institutionen för matematik och datavetenskap (from 2013); Karlstads universitet/Avdelningen för datavetenskap

    Author : Benjamin Salomonsson; [2022]
    Keywords : New Radio NR ; Shared Channel; Channel Coding; Low Density Parity-Check LDPC ; Min-Sum Algorithm MSA ; Graphics Processing Unit GPU ; Compute Unified Device Architecture CUDA ;

    Abstract : Low-Density Parity-Check (LDPC) codes are linear error-correcting codes used to establish reliable communication between units on a noisy transmission channel in mobile telecommunications. LDPC algorithms detect and recover altered or corrupted message bits using sparse parity-check matrices in order to decipher messages correctly. READ MORE
