1. Robust Non-Linear State Estimation for Underwater Acoustic Localization : Expanding on Gaussian Mixture Methods
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : Robust state estimation solutions must deal with faulty measurements, called outliers, and unknown data associations, which lead to multiple feasible hypotheses. Take, for instance, the scenario of tracking two indistinguishable targets based on position measurements, where each measurement could refer to either of the targets or even be a faulty reading.

2. 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

3. Sum-Product Network in the context of missing data
University essay from KTH/Matematisk statistikAbstract : In recent years, the interest in new Deep Learning methods has increased considerably due to their robustness and applications in many fields. However, the lack of interpretability of these models and the lack of theoretical knowledge about them raises many issues. It is in this context that sum product network models have emerged.

4. Evaluation of flexible SPA based LPDC decoder using hardware friendly approximation methods
University essay from Lunds universitet/Institutionen för elektro- och informationsteknikAbstract : 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

5. Machine Intelligence in Decoding of Forward Error Correction Codes
University essay from KTH/Teknisk informationsvetenskapAbstract : A deep learning algorithm for improving the performance of the Sum-ProductAlgorithm (SPA) based decoders is investigated. The proposed Neural NetworkDecoders (NND) [22] generalizes the SPA by assigning weights to the edges ofthe Tanner graph. We elucidate the peculiar design, training, and working of theNND. READ MORE
