WebApr 7, 2011 · Let's assume I want to have a possibility of detecting 4-bit errors and recovering 2-bit errors. What the Hamming distance should be then? I wonder if it should be d = Max{2r+1, r+1} or d = s + r, where s is 4 and r is 2? ... When you have a minimum hamming distance of length 5 you can detect at max only 4 bit errors because if there … 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
