WebA simple parity-check code is a single-bit error-detecting code in which n = k + 1 with d min = 2. A simple parity-check code can detect an odd number of errors. All Hamming codes discussed in this book have d min = 3. The relationship between m and n in these codes is n = 2m - 1. Cyclic codes are special linear block codes with one extra property. WebHamming's (7,4) algorithm can correct any single-bit error, or detect all single-bit and two-bit errors. In other words, the minimal Hamming distance between any two correct codewords is 3, and received words can be correctly decoded if they are at a distance of at most one from the codeword that was transmitted by the sender.

How can you tell if a error is single or double? The Hamming code can be modified to correct a single error and detect double errors by adding a parity bit as the MSB, which is the XOR of all other bits. How a single bit error can be detected and corrected?
