However, the Hamming code cannot … Webber of tolerable bit errors in a code. When each two code words diﬀer in at least d min bits, one can deter-mine the number of faults that are safely detected and corrected. A decoder that exclusively detects errors, is able to detect d min − 1 erroneous bits. When the decoder corrects errors, (d min −1)/2 bit errors can be corrected.

Hamming Codes: Detecting and Correcting Errors

WebThe minimum Hamming distance between "000" and "111" is 3, which satisfies 2k+1 = 3. Thus a code with minimum Hamming distance d between its codewords can detect at most d-1 errors and can correct ⌊(d-1)/2⌋ errors. The latter number is also called the packing radius or the error-correcting capability of the code.
