Hamming weight function

WebAs usual, the Hamming cube is the graph whose vertex set is Fn 2, where ad-jacency means having Hamming distance one. The j-th level of the cube, for 0 ≤ j ≤ n, is the set of vertices of Hamming weight j. Let f,g : Fn 2 → R be real functions on … WebThe Hamming distance between 1-D arrays u and v, is simply the proportion of disagreeing components in u and v. If u and v are boolean vectors, the Hamming distance is c 01 + c 10 n where c i j is the number of occurrences of u [ k] = i and v [ k] = j for k < n. Parameters: u(N,) array_like Input array. v(N,) array_like Input array.

The generalized Hamming weights of linear codes have attracted scholars' attention since Wei used them to characterize the cryptography performance of a linear code over the wire-tap channel of type II in 1991. Generally speaking, it is hard to determine linear codes' generalized Hamming weights, especially the weight hierarchy.

WebAmong the most important of these are the Hamming weight, algebraic normal form (ANF), nonlinearity, affine transformation and the Walsh transform W (f) for a … WebNotice how the Hamming weight of the systematic part (i.e., the single systematic bit) determines the code for the non-systematic part. The combined Hamming weight of the systematic and non-systematic part is always two, though. So, we obtain a subset of the 2-of-5 code comprising only eight symbols (while 5 2 = 10). Hence we can still encode ...

WebThe Hamming window is an extension of the Hann window in the sense that it is a raised cosine window of the form (A3.10) with a corresponding spectrum of the form (A3.11) The parameter a permits the optimization of the destructive sidelobe cancellation mentioned in the description of the Hann window. WebC ⊥ is called the dual code of C, and any generator matrix for C ⊥ is called a parity check matrix for C. We commonly endow Fn with the Hamming metric, i.e. the weight of a vector is the number of non-zero elements in it. The central operation of a linear code is then “decoding”: given a linear code C ⊂ Fn and a “received word” r ...
