Dear All,
I did manage to generate a low-density pairty-check matrix H, wit
respecting the conditions of colunms and rows weight. The problem that
am facing is that H is singular (det(H)=0) and even when I writ
H=[H1|H2], I get also det(H2)=0, which I wont be able to calculate th
generator matrix G of my code. It seems that the number of 1s in m
colunms is even. But I saw in some textbooks where they use even number o
1s in each colunms.
Am I using the right method to calculate G? Or can I find other tools t
calculate G. Or what is the problem?
Please I am strugling and I need urgent help.
Best regards
