Abstract
A method and system are provided for error correction. After row encoding and column encoding, additional codeword data (ACD) and modified parity (P') may be concurrently created, for each of a plurality of modified column codewords (CCW′), by multiplying initial calculated parity P by a generator matrix G. Each CCW′ may include an ACD portion and a P′ portion such that each bit in the P′ portion of a selected CCW′ is present in the ACD portion for one of the other CCW′. In contrast to known approaches, the method and system may provide modified column codewords such that all data and parity bits are present in two codewords while using only two types of codewords, and without using extra parity-on-parity bits. In a set of modified column codewords, each bit in the modified parity in one modified codeword is present in another codeword.
