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 … originates meaning in hindi

WebThe CRC encoding process involves dividing D(x). xr by G(x) to obtain the quotient p(x) and the remainder R(x), which is of degree r–1. This results in the equation D(x) · x r = G(x) · p(x) + R(x).Then the transmitted polynomial T(x) = G(x) · p(x) = D(x) · x r – R(x).Because the addition of coefficients is an XOR operation and the product is an AND operation, it turns … WebCRC polynomials at a data word size of 48 bits, which is a representative length for many embedded networks.
