WebHamming distance This number is the Hamming distance between x and y. The Hamming distance is a genuine metric on the codespace An. It is clear that it is symmetric and that d H(x;y) = 0 if and only if x = y. The Hamming distance d H(x;y) should be thought of as the number of errors required to change x into y (or, equally well, to change y ... WebHamming distance between any two valid code words is at least 2. In the diagram above, we’re using “even parity” where the added bit is chosen to make the total number of 1’s in the code word even. Can we correct detected errors? Not yet… If D is the minimum Hamming distance between code words, we can detect up to (D-1)-bit errors
