WebbHamming distance. Hamming distance measures binary data strings. The distance between two strings of equal length is the number of bit positions at which the bits are different. For example, suppose there are two strings, 1101 1001 and 1001 1101. 11011001 ⊕ 10011101 = 01000100. Since, this contains two 1s, the Hamming distance, d … WebbRichard Hamming, in Classical and Quantum Information, 2012. Example. The Hamming distance of two codewords. Consider the binary alphabet {0, 1}, and let the two codewords be v i = (010110) and V j = (011011). The Hamming distance between the two codewords is d(v i, v j) = 3. Indeed, if we number the bit position in each n-tuple from left to right as 1 to …
