1. Faster than Nyquist Signaling with Spatial Coupling
University essay from Lunds universitet/Institutionen för elektro- och informationsteknikAbstract : 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).

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 datavetenskapAbstract : 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

3. Implementation of Low-Density Parity-Check codes for 5G NR shared channels
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)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. Enhancing the Decoding of Short LDPC Codes with Stochastic Sequences
University essay from Lunds universitet/Institutionen för elektro- och informationsteknikAbstract : Low-Density Parity-Check (LDPC) codes are one of the most popular codes used in nowadays’ communication due to their high coding efficiency at low decoding complexity. With these characteristics, LDPC codes are suitable for high-speed information transmission systems. READ MORE

5. Spatially Coupled Codes in Turbo Equalization
University essay from Lunds universitet/Institutionen för elektro- och informationsteknikAbstract : In this thesis we investigate the application of spatial coupling in turbo equalization. We show that with spatial coupling we can have a fresh perspective on the trade-off between performance in the waterfall and error floor region often encountered in the choice of codes for turbo equalization.
