pyldpc.encode

pyldpc.encode(tG, v, snr, seed=None)

Encode a binary message and adds Gaussian noise.

Parameters

tG: array or scipy.sparse.csr_matrix (m, k). Transposed coding matrix

obtained from `pyldpc.make_ldpc`.

v: array (k, ) or (k, n_messages) binary messages to be encoded.

snr: float. Signal-Noise Ratio. SNR = 10log(1 / variance) in decibels.

Returns

y: array (n,) or (n, n_messages) coded messages + noise.
