pyldpc.make_ldpc

pyldpc.make_ldpc(n_code, d_v, d_c, systematic=False, sparse=True, seed=None)

Create an LDPC coding and decoding matrices H and G.

Parameters

n_code: int, Length of the codewords.

d_v: int, Number of parity-check equations including a certain bit.

d_c: int, Number of bits in the same parity-check equation. d_c Must be

greater or equal to d_v and must divide n.

seed: int, seed of the random generator.

systematic: boolean, default False. if True, constructs a systematic

coding matrix G.
