A Unifying Framework to Construct QC-LDPC Tanner Graphs of Desired Girth
Roxana Smarandache, David G. M. Mitchell
This paper presents a unifying framework to construct low-density parity-check (LDPC) codes with associated Tanner graphs of desired girth. Towards this goal, we highlight the role…
Necessary and Sufficient Girth Conditions for LDPC Tanner Graphs with Denser Protographs
Anthony Gómez-Fonseca, Roxana Smarandache, David G. M. Mitchell
This paper gives necessary and sufficient conditions for the Tanner graph of a quasi-cyclic (QC) low-density parity-check (LDPC) code based on the all-one protograph to have girth…
Necessary and Sufficient Girth Conditions for Tanner Graphs of Quasi-Cyclic LDPC Codes
Roxana Smarandache, David G. M. Mitchell
This paper revisits the connection between the girth of a protograph-based LDPC code given by a parity-check matrix and the properties of powers of the product between the matrix a…
