Design of High-Rate LDPC Codes Based on Matroid Theory

In this letter, sufficient conditions for the determination of the girth are studied from the perspective of matroid theory. The girth of a Tanner graph is at least 2(t 1 + 2) if t 1 specific conditions are simultaneously met. A novel method of constructing high-rate low-density parity-check (LDPC)...
