Summary:Methods, apparatus, and systems are provided to encode a low-density parity-check codeword for transmission in a communications channel. In an embodiment, the encoding may include partially computing parity-check bits in response to receiving a block of message bits before obtaining all the message bits for the low-density parity-check codeword, including updating previously partially computed parity-check bits that depend on the received block.
