Nettet1 The first-order binary Reed-Muller code is a [ 16, 5, 8] code and if we shorten this code by deleting the over-all parity check bit and taking only the remaining codewords of even weight, then we are left with a [ 15, 4, 8] linear binary code. Can this be shortened further to a [ 13, 4, 6] linear code? – Dilip Sarwate Nov 7, 2012 at 4:47 1
Nettet1. jan. 2012 · Recently, binary linear codes were associated with binomial ideals. We show that each linear code can be described by a binomial ideal given as the sum of a … NettetIn order to show that the code is linear, we only need to show that it is closed under addition. In other words, we need to show that if $a, b \in E$, then $a + b \in E$. Note …

And you don't need to worry about scalar multiples in the binary case, but you do need to argue that the $0$ vector is in the code for it to be linear. $\endgroup$ – xxxxxxxxx
NettetIn linear algebra terms, the dual code is the annihilator of C with respect to the bilinear form . The dimension of C and its dual always add up to the length n : A generator matrix for the dual code is the parity-check matrix for the original code and vice versa. The dual of the dual code is always the original code. Self-dual codes [ edit]
A linear code of length n and dimension k is a linear subspace C with dimension k of the vector space $${\displaystyle \mathbb {F} _{q}^{n}}$$ where $${\displaystyle \mathbb {F} _{q}}$$ is the finite field with q elements. Such a code is called a q-ary code. If q = 2 or q = 3, the code is described as a binary code, or a … Se mer In coding theory, a linear code is an error-correcting code for which any linear combination of codewords is also a codeword. Linear codes are traditionally partitioned into block codes and convolutional codes, … Se mer Codes in general are often denoted by the letter C, and a code of length n and of rank k (i.e., having k code words in its basis and k rows in its generating matrix) is generally referred to … Se mer A code is defined to be equidistant if and only if there exists some constant d such that the distance between any two of the code's distinct … Se mer As a linear subspace of $${\displaystyle \mathbb {F} _{q}^{n}}$$, the entire code C (which may be very large) may be represented as the Se mer As the first class of linear codes developed for error correction purpose, Hamming codes have been widely used in digital communication … Se mer Lemma (Singleton bound): Every linear [n,k,d] code C satisfies $${\displaystyle k+d\leq n+1}$$. A code C whose parameters satisfy k+d=n+1 is called maximum distance separable or MDS. Such codes, when they exist, are in some … Se mer Some examples of linear codes include: • Repetition codes • Parity codes • Cyclic codes Se mer halti pallas ii w x-stretch warmNettet4. jun. 2024 · This theorem gives us conditions on a matrix H that tell us when the minimum weight of the code formed by the null space of H is 2. We can also determine when the minimum distance of a linear code is 3 by examining the corresponding matrix.

We commonly endow Fn with the Hamming metric, i.e. the weight of a vector is the number of non-zero elements in it.
