Protograph-Based Generalized LDPC Codes: Enumerators, Design, and Applications
Among the recent advances in the area of low-density parity-check (LDPC) codes, protograph-based LDPC codes have the advantages of a simple design procedure and highly structured encoders and decoders. These advantages can also be exploited in the design of protograph-based generalized LDPC (G-LDPC) codes. In this dissertation we provide analytical tools which aid the design of protographbased ...
متن کاملOn the Tanner Graph Cycle Distribution of Random LDPC, Random Protograph-Based LDPC, and Random Quasi-Cyclic LDPC Code Ensembles
Random bipartite graphs, random lifts of bipartite protographs, and random cyclic lifts of bipartite protographs are used to represent random low-density parity-check (LDPC) codes, randomly constructed protograph-based LDPC codes, and random quasi-cyclic (QC) LDPC codes, respectively. In this paper, we study the distribution of cycles of different length in all these three categories of graphs....
متن کاملEnsemble Trapping Set Enumerators for Protograph-Based LDPC Codes
Protograph-based LDPC codes have the advantages of a simple design (or search) procedure and highly structured encoders and decoders. Recently, techniques for finding asymptotic trapping set enumerators in regular and irregular LDPC code ensembles was published [1]. In this paper, finite-length ensemble trapping set enumerators for protographbased LDPC codes are obtained. The asymptotic results...
متن کاملNotes: Finite-length Protograph-based Spatially Coupled LDPC Codes
The finite-length performance of multi-edge spatially coupled low-density parity-check (SC-LDPC) codes is analyzed over the binary erasure channel (BEC). Existing scaling laws are extended to arbitrary protograph base matrices including puncturing patterns and multiple edges between nodes. Compared to more involved rate-1/2 structures proposed to improve the threshold to minimum distance trade-...
متن کاملLDPC Code Design for Min-Sum Based Decoding
We consider the problem of designing low-density parity-check (LDPC) codes for min-sum decoding. We wish to find the LDPC ensemble with the best asymptotic performance. In [1], [2], Amraoui and Urbanke proposed an optimization scheme where a combination of density evolution and extrinsic information transfer (EXIT) charts is used to design LDPC codes for the belief propagation decoding algorith...
