1. 1. Faster than Nyquist Signaling with Spatial Coupling

   Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

   Författare :Haoran Liu; Lingwei Zhang; [2022]
   Nyckelord :Technology and Engineering;

   Sammanfattning : 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. Spatially Coupled Codes in Turbo Equalization

   Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

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

   Sammanfattning : 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.
