摘要： A system and method for decoding multi-dimensional encoded data. A set of multi-dimensional encoded data may be received encoding each input bit in a set of input bits by multiple different component codes in multiple different encoding dimensions. The multi-dimensional data may potentially have errors. A map may be used to locate each set of intersection bits that encode the same input bit by multiple unsolved component codes. The unsolved component codes may be decoded using one or a plurality of tested error correction hypotheses that yields a decoding success, where each hypothesis correcting a different set of intersection bits for a different input bit. The successful hypothesis may be applied for correcting the multi-dimensional encoded data.

摘要： A system and method is provided for decoding a set of bits using a plurality of hypotheses, for example, each independently tested on-the-fly. Initial bit states and associated reliability metrics may be received for the set of bits. A current hypothesis may be decoded for correcting the set of bits, wherein the current hypothesis defines different bit states and associated reliability metrics for the set of bits. If decoding the current hypothesis is not successful, a subsequently ordered hypothesis may be decoded, wherein the hypotheses are ordered such that their associated reliability metric is a monotonically non-decreasing sequence. Decoding may proceed iteratively until the current hypothesis is successful.

摘要： A system and method for using a cyclic redundancy check (CRC) to evaluate error corrections. A set of data and initial CRC values associated therewith may be received. The set of data by changing a sub-set of the data may be corrected. Intermediate CRC values may be computed for the entire uncorrected set of data in parallel with said correcting. Supplemental CRC values may be computed for only the sub-set of changed data after said correcting. The intermediate and supplemental CRC values may be combined to generate CRC values for the entire corrected set of data. The validity of the corrected set of data may be evaluated by comparing the combined CRC values with the initial CRC values.
