WebJan 30, 2014 · 1 Answer. Sorted by: 3. When the code is linear, there is no need to go over all pairs of codewords, due to linearity. Indeed, since d ( x, y) = d ( x ⊕ y, 0) and for any two codewords x, y ∈ C, linearity implies that x ⊕ y ∈ C, we see that the minimal distance is the minimal weight of a non-zero codeword.
