Abstract
A method and apparatus for the generation of a signal flag in response to illegal channel code patterns from an information channel, the signal flag may typically be used as an erasure flag by a subsequent error correction decoder. This erasure flag, being indicative of a data error position which can then be fed into a utilization circuit such as an error correction logic for performance improvement. In particular, a Miller-squared channel code format decoder in accordance with the present invention can easily and inexpensively provide error position information thereby enhancing error correction power, such as that of a Reed-Solomon error correction code.
