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. History and applications grand isle golf cart rental
