ABSTRACT:
An ordered list of CRC syndromes, corresponding to single-bit errors, is used to identify an error bit position, enabling correction of the bit at the identified error bit position. For instance, the syndrome corresponding to an error at the fifth bit position is in the fifth position in the list. A syndrome for a received block is compared sequentially with the members of the list until a match is found. When a match is found, the corresponding bit of the received block is inverted.
