Webcrcgenerator = comm.CRCGenerator (Name,Value) crcgenerator = comm.CRCGenerator (poly,Name,Value) Description crcgenerator = comm.CRCGenerator creates a CRC code generator System object. This object generates CRC bits according to a specified generator polynomial and appends them to the input frame. example A CRC is a checksum in a strict mathematical sense, as it can be expressed as the weighted modulo-2 sum of per-bit syndromes, but that word is generally reserved more specifically for sums computed using larger moduli, such as 10, 256, or 65535. See more The 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 See more There are several standard variations on CRCs, any or all of which may be used with any CRC polynomial. Implementation variations such as endianness and CRC presentation only affect the mapping of bit strings to the coefficients of • To … See more The error-detection ability of a CRC depends on the degree of its key polynomial and on the specific key polynomial used. The "error polynomial" $${\displaystyle E(x)}$$ is the symmetric difference of the received message codeword and the … See more In general, computation of CRC corresponds to Euclidean division of polynomials over GF(2): See more Since the coefficients are constrained to a single bit, any math operation on CRC polynomials must map the coefficients of the result to either … See more Polynomial representations Example of CCITT 16-bit Polynomial in the forms described (bits inside square brackets are included in the word representation; bits … See more • Barrett reduction • Error correcting code • List of checksum algorithms See more
