LDPC Code Designs, Constructions, and Unification

In this book, leading authorities unify algebraic- and graph-based LDPC code designs and constructions into a single theoretical framework.

Written by leading authorities, this accessible and self-contained text unifies algebraic- and graph-based LDPC code designs and constructions into a single theoretical framework. It is essential reading for electrical engineers and computer scientists wanting to design information and communications systems with better error-control capabilities.Written by leading experts, this self-contained text provides systematic coverage of LDPC codes and their construction techniques, unifying both algebraic- and graph-based approaches into a single theoretical framework (the superposition construction). An algebraic method for constructing protograph LDPC codes is described, and entirely new codes and techniques are presented. These include a new class of LDPC codes with doubly quasi-cyclic structure, as well as algebraic methods for constructing spatially and globally coupled LDPC codes. Authoritative, yet written using accessible language, this text is essential reading for electrical engineers, computer scientists and mathematicians working in communications and information theory.
