Abstract
A system for correcting multiple simultaneously erroneous channels within a plurality of parallel data channels including redundant channels. At the receiving side a group of syndrome generators each applies a secondary parity check matrix for producing corresponding groups of syndrome bit streams. If the error is correctable, one or more of the syndrome bit streams is added to corresponding code bit streams. If a syndrome bit stream indicates an error in a non-applicable code bit channel, or otherwise indicates too many errors, it remains unused. Decoders with feedback (restoration of syndromes after correction) and feedback-free decoders are possible.
