Crc hamming weight table
WebAs for all digital codes, the error detection and correctionabilities of polynomial codes are determined by the minimum Hamming distanceof the code. Since polynomial codes are linear codes, the minimum Hamming distance is equal to the minimum weight of any non-zero codeword. WebJul 6, 2024 · The minimal distance of a code is the minimal weight of a non-zero codeword. The "Hamming weights for data word size 48 bits" for a specific number n of corrupted bits is in fact the number of polynomials p …
