Sparse Graphs for Belief Propagation Decoding of Polar Codes
Sebastian Cammerer, Moustafa Ebada, Ahmed Elkelesh +1
We describe a novel approach to interpret a polar code as a low-density parity-check (LDPC)-like code with an underlying sparse decoding graph. This sparse graph is based on the en…
Mitigating Clipping Effects on Error Floors under Belief Propagation Decoding of Polar Codes
Ahmed Elkelesh, Sebastian Cammerer, Moustafa Ebada +1
In this work, we show that polar belief propagation (BP) decoding exhibits an error floor behavior which is caused by clipping of the log-likelihood ratios (LLR). The error floor b…
Scattered EXIT Charts for Finite Length LDPC Code Design
Moustafa Ebada, Ahmed Elkelesh, Sebastian Cammerer +1
We introduce the Scattered Extrinsic Information Transfer (S-EXIT) chart as a tool for optimizing degree profiles of short length Low-Density Parity-Check (LDPC) codes under iterat…
