New Density Evolution Approximation for LDPC and Multi-Edge Type LDPC Codes
Sachini Jayasooriya, Mahyar Shirvanimoghaddam, Lawrence Ong +2
This paper considers density evolution for lowdensity parity-check (LDPC) and multi-edge type low-density parity-check (MET-LDPC) codes over the binary input additive white Gaussia…
A Joint Optimization Technique for Multi-Edge Type LDPC Codes
Sachini Jayasooriya, Mahyar Shirvanimoghaddam, Lawrence Ong +1
This paper considers the optimization of multi-edge type low-density parity-check (METLDPC) codes to maximize the decoding threshold. We propose an algorithm to jointly optimize th…
Optimization of Graph Based Codes for Belief Propagation Decoding
Sachini Jayasooriya, Sarah J. Johnson, Lawrence Ong +1
A low-density parity-check (LDPC) code is a linear block code described by a sparse parity-check matrix, which can be efficiently represented by a bipartite Tanner graph. The stand…
