Abstract
The present disclosure describes methods and apparatus for generating expanded code words to support error correction in a data communication system. In some aspects data to be encoded and a first subset of bits of a first bit sequence are obtained. A first combined bit sequence is generated by combining the data and the first subset of bits. A first code word is generated by applying an error correcting code to the first combined bit sequence. The first code word is combined with the first bit sequence, resulting in first encoded data that includes both first parity information and the data. The generating, applying, and combining are repeated with a second subset of bits of a second bit sequence, resulting in second encoded data that includes both second parity information and the data, the second encoded data being based on a second code word rather than the first code word.
