Various embodiments of the present invention provide systems and methods for stochastic stream decoding of binary LDPC codes. For example, a data decoder circuit is discussed that includes a number of variable nodes and check nodes, with serial connections between the variable nodes and the check nodes. The variable nodes are each operable to perform a real-valued computation of a variable node to check node message for each neighboring check node. The check nodes are operable to perform a real-valued computation of a check node to variable node message for each neighboring variable node. The messages are passed iteratively between the variable nodes and the check nodes.

In one embodiment, a communications system has a write path and a read path. In the write path, a local/global interleaver interleaves a user data stream, and an error-correction (EC) encoder encodes the user data stream to generate an EC codeword. A local/global de-interleaver de-interleaves the parity bits of the EC codeword, and both the original un-interleaved user data and the de-interleaved parity bits are transmitted via a noisy channel. In the read path, a channel detector recovers channel soft-output values corresponding to the codeword. A local/global interleaver interleaves the channel values, and an EC decoder decodes the interleaved values to recover the original codeword generated in the write path. A de-multiplexer de-multiplexes the user data from the parity bits. Then, a local/global de-interleaver de-interleaves the user data to obtain the original sequence of user data that was originally received at the write path.
