Analysis of Coupled Scalar Systems by Displacement Convexity
Rafah El-Khatib, Nicolas Macris, Tom Richardson +1
Potential functionals have been introduced recently as an important tool for the analysis of coupled scalar systems (e.g. density evolution equations). In this contribution, we inv…
The Effect of Saturation on Belief Propagation Decoding of LDPC Codes
Shrinivas Kudekar, Tom Richardson, Aravind Iyengar
We consider the effect of LLR saturation on belief propagation decoding of low-density parity-check codes. Saturation occurs universally in practice and is known to have a signific…
Threshold Saturation on BMS Channels via Spatial Coupling
Shrinivas Kudekar, Cyril Measson, Tom Richardson +1
We consider spatially coupled code ensembles. A particular instance are convolutional LDPC ensembles. It was recently shown that, for transmission over the binary erasure channel,…
