ldpc encoding

please give algorithm for ldpc encoding and also matlab code

[Information merged from duplicate post]

LDPC codes BER simulation under AWGN channel.

can i get algorithm for making H matrix in makeLdpc function

here fecldpcenc cant be used.

According to the ldpc encoding documentation,

I = randint(1,43200); % INFORMATION BITS
H = dvbs2ldpc(2/3);
l = fec.ldpcenc(H);
codeword = encode(l,I);
Hope so, this code may help u to perform LDPC encoding. Please be specify about ur actual problem. So that, we can help u in better way.
