1. 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.

2. Implementation of 3GPP LTE QPP Interleaver for SiLago
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : Modern wireless communication systems have seen an increased usage of various channel coding techniques to facilitate improved throughput and latency. Interleavers form an integral part of these coding techniques and play a critical role by making the communication more robust and resilient to noise and other interference. READ MORE

3. Comparison of various concatenated convolutional code ensembles under spatial coupling
University essay from Lunds universitet/Institutionen för elektro- och informationsteknikAbstract : 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

4. Turbo Decoder with early stopping criteria
University essay from Lunds universitet/Institutionen för elektro- och informationsteknikAbstract : The turbo code used in the 3GPP Long Term Evolution(LTE) standard have been chosen specifically to simplify parallel turbo decoding and thus achieving higher throughputs. The higher data rates however leads to an increased computational complexity and thus a higher power and energy consumption of the decoder. READ MORE

5. Low complexity algorithms for faster-than-Nyquistsign : Using coding to avoid an NP-hard problem
University essay from KTH/Optimeringslära och systemteoriAbstract : This thesis is an investigation of what happens when communication links are pushed towards their limits and the data-bearing-pulses are packed tighter in time than previously done. This is called faster-than-Nyquist (FTN) signaling and it will violate the Nyquist inter-symbol interference criterion, implying that the data-pulsesare no longer orthogonal and thus that the samples at the receiver will be dependent on more than one of the transmitted symbols.
