Trapping Sets of Iterative Decoders for Quantum and Classical Low-Density Parity-Check Codes
… with failure configurations, known as \emph{trapping sets} of classical and quantum LDPC codes when decoded with iterative message passing decoding algorithms, and the \emph{error floor phenomenon} - the degradation of logical error rate performance at low physical noise regime. The study of …

The Analysis of Error Floor and Graphical Structure of LDPC Codes
… thesis, we analyze the graphical structure of trapping sets and study their relationships to short cycles and to the code parameters such as block length and degree distributions. As a result, we develop new characterizations of trapping sets and novel techniques to efficiently find them.Our …

Error Floor Analysis of Quasi-Cyclic LDPC and Spatially Coupled-LDPC Codes and Construction of Codes with Low Error Floor
… main role in the average number of cycles and trapping sets in the Tanner graph of finite-length SC-LDPC codes. This, in fact, gives an insight into the error floor performance of protograph-based SC-LDPC codes, and demonstrates the superiority of these codes in the error floor region, compared …

Estimating the Performance of Optical Fibre Communication Systems
… belief propagation that targets problematic sets found in their Tanner graph representation, and called trapping sets. The framework involves first locating the trapping sets, then determining the ones that result in the highest error rates, and lastly marking the relevant Tanner graph edges …
