High-Rate Spatially Coupled LDPC Codes Based on Massey's Convolutional Self-Orthogonal Codes
Daniel J. Costello, Min Zhu, David G. M. Mitchell +1
In this paper, we study a new class of high-rate spatially coupled LDPC (SC-LDPC) codes based on the convolutional self-orthogonal codes (CSOCs) first introduced by Massey. The SC-…
LDPC Codes for Quantitative Group Testing with a Non-Binary Alphabet
Mgeni Makambi Mashauri, Alexandre Graell i Amat, Michael Lentmaier
We propose and analyze a novel scheme based on LDPC codes for quantitative group testing. The key underlying idea is to augment the bipartite graph by introducing hidden non-binary…
Low-Density Parity-Check Codes and Spatial Coupling for Quantitative Group Testing
Mgeni Makambi Mashauri, Alexandre Graell i Amat, Michael Lentmaier
A non-adaptive quantitative group testing (GT) scheme based on sparse codes-on-graphs in combination with low-complexity peeling decoding was introduced and analyzed by Karimi et a…
Robust Performance Over Changing Intersymbol Interference Channels by Spatial Coupling
Mgeni Makambi Mashauri, Alexandre Graell i Amat, Michael Lentmaier
We show that spatially coupled low-density parity-check (LDPC) codes yield robust performance over changing intersymbol interfere (ISI) channels with optimal and suboptimal detecto…
On the Universality of Spatially Coupled LDPC Codes Over Intersymbol Interference Channels
Mgeni Makambi Mashauri, Alexandre Graell i Amat, Michael Lentmaier
In this paper, we derive the exact input/output transfer functions of the optimal a-posteriori probability channel detector for a general ISI channel with erasures. Considering thr…
Improving the Thresholds of Generalized LDPC Codes with Convolutional Code Constraints
Muhammad Umar Farooq, Michael Lentmaier, Alexandre Graell i Amat
CC-GLPDC codes are a class of generalized low-density parity-check (GLDPC) codes where the constraint nodes (CNs) represent convolutional codes. This allows for efficient decoding…
