• ### Hamming Distance - an overview

The Hamming distance between two codewords is defined as the number of elements in which they differ. The minimum distance dmin of a linear block code is the smallest Hamming distance between any two different codewords, and is equal to the minimum Hamming weight of the non-zero codewords in the code. Example 10.4.
