A data decoder for decoding an asynchronous incoming data stream includes a bit engine receiving information describing the incoming data stream and generating a decoded data stream. In one embodiment, the bit engine includes a best-fit bit analysis block performing a pattern match operation for each data bit of the incoming data stream using the information describing the incoming data stream. The best-fit bit analysis block is operative to find a pattern of data bits that best matches the data bits in the incoming data stream. The bit engine further includes a missing bit insertion block to insert a dummy bit for each data bit where the best-fit bit analysis block cannot find a pattern match. An error correction block performs forward error correction on the decoded data stream, including the dummy bits, to generate a corrected outgoing data stream.
