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. Enhancing the Decoding of Short LDPC Codes with Stochastic Sequences

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

   Author : Yuyuan Gu; Haien Li; [2021]
   Keywords : 5G; channel coding; LDPC codes; stochastic decoding; stochastic computation; Technology and Engineering;

   Abstract : 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

4. 3. Spatially Coupled Codes in Turbo Equalization

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

   Author : Mgeni Makambi Mashauri; [2019]
   Keywords : Turbo equalization; spatial coupling; waterfall versus error floor; codes on graphs; iterative receivers; LDPC codes in turbo equalization; Technology and Engineering;

   Abstract : 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.

5. 4. Low Density Parity Check Encoder and Decoder on SiLago Coarse Grain Reconfigurable Architecture

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Weijiang Kong; [2019]
   Keywords : LDPC; CGRA; Reconfigurable architecture; VLSI design; ASIC; LDPC; CGRA; Konfigurerbar arkitektur; VLSI design; ASIC;

   Abstract : Low density parity check (LDPC) code is an error correction code that has been widely adopted as an optional error correcting operation in most of today’s communication protocols. Current design of ASIC or FPGA based LDPC accelerators can reach Gbit/s data rate. READ MORE

6. 5. Evaluation of flexible SPA based LPDC decoder using hardware friendly approximation methods

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

   Author : Afshin Seraj; Deepak Yadav; [2017]
   Keywords : forward-backward; SPA; soft-xor; sum product algorithm; approximation; decoder; LDPC; Technology and Engineering;

   Abstract : Due to computation-intensive nature of LDPC decoders, a lot of research is going towards efficient implementation of their original algorithm (SPA). As "Min-Sum" approximation is basically an overestimation of SPA, this thesis investigates more accurate, yet area efficient, approximations of SPA, to select an optimum one. READ MORE
