摘要:
Methods and apparatus for generating cyclic redundancy checks (CRCs). In one aspect of the present invention, a plurality of cyclic redundancy checks are calculated based upon a plurality of bits by using a selected cyclic redundancy check generator polynomial, at least one cyclic redundancy check is calculated based upon a first subset of the plurality of bits with a certain bit ordering, and at least another cyclic redundancy check is calculated based upon a second subset of the plurality of bits with a different bit ordering. The second subset of bits may overlap with the first subset of bits. In another aspect, a plurality of cyclic redundancy checks are calculated based upon a plurality of bits by using a plurality of different cyclic redundancy check generator polynomials. A first cyclic redundancy check generator polynomial is used for calculating a first cyclic redundancy check based upon a first plurality of bits, and a second cyclic redundancy check generator polynomial is used for calculating a second cyclic redundancy check based upon a second plurality of bits.
