An investigation of SUDOKU-inspired non-linear codes with local constraints
Jossy Sayir, Joned Sarwar
Codes with local permutation constraints are described. Belief propagation decoding is shown to require the computation of permanents, and trellis-based methods for computing the p…
Challenges and some new directions in channel coding
Erdal Arikan, Najeeb ul Hassan, Michael Lentmaier +2
Three areas of ongoing research in channel coding are surveyed, and recent developments are presented in each area: spatially coupled Low-Density Parity-Check (LDPC) codes, non-bin…
Non-binary LDPC decoding using truncated messages in the Walsh-Hadamard domain
Jossy Sayir
The Extended Min-Sum (EMS) algorithm for non-binary low-density parity-check (LDPC) defined over an alphabet of size operates on truncated messages of length to achieve a…
Density Evolution for SUDOKU Codes on the Erasure Channel
Caroline Atkins, Jossy Sayir
Codes based on SUDOKU puzzles are discussed, and belief propagation decoding introduced for the erasure channel. Despite the non-linearity of the code constraints, it is argued tha…
The Role Model Estimator Revisited
Jossy Sayir
We re-visit the role model strategy introduced in an earlier paper, which allows one to train an estimator for degraded observations by imitating a reference estimator that has acc…
EXIT Chart Approximations using the Role Model Approach
Jossy Sayir
Extrinsic Information Transfer (EXIT) functions can be measured by statistical methods if the message alphabet size is moderate or if messages are true a-posteriori distributions.…
