Cyclic Redundancy Check - an overview ScienceDirect Topics

WebA CRC is a long-division remainder. You add the CRC to the message, and the whole thing (message+CRC) is a multiple of the given CRC polynomial. To check the CRC, you can either check that the CRC matches the recomputed value, or you can check that the remainder computed on the message+CRC is 0. This latter approach is used by a lot of … WebThe cyclic redundancy check (CRC) is based on division in the ring of polynomials over the finite field GF (2) (the integers modulo 2 ), that is, the set of polynomials where each coefficient is either zero or one, and arithmetic operations wrap around.
