Generation of LDPC Check Matrix Using MadHG Rules with Code Implementation
Implementation of MadHG method for constructing LDPC check matrix H with row weight 6, column weight 3, and row count half of column count (preferably larger row numbers). The algorithm ensures no girth-4 cycles between any two columns in H and produces corresponding generator matrix G satisfying mod(G*H, 2)=0. Function call: [H, G] = MadHG(m, n, x), where x=1 yields identity matrix in left half of G, x=2 in right half.
