Exact Erasure Channel Density Evolution for Protograph-Based Generalized LDPC Codes
(2009) IEEE International Symposium on Information Theory (ISIT), 2009 p.566-570- Abstract
- We derive explicit density evolution equations for protograph-based generalized LDPC codes on the binary erasure channel. They are obtained from an analysis of multi-dimensional input/output transfer functions of the component decoders. Belief propagation decoding with optimal component APP decoders is considered. Based on the resulting transfer functions, a threshold analysis is performed for some protograph examples.
