Abstract
A novel algorithm to construct structured LDPC codes based on graph connectivity and cycle quality is proposed. The performance of the constructed QC-LDPC and IRA codes is investigated and a performance improvement in the error floor region is demonstrated. The code constructions provided are flexible in rate and length and demonstrate that the enhanced EMD-driven PEG-based approach proposed may be applied to a number of other structured LDPC code classes, given consideration of correct constraints of the construction.
