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 … See more 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, … See more As the first class of linear codes developed for error correction purpose, Hamming codes have been widely used in digital communication systems. For any positive integer See more 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 … See more Some examples of linear codes include: • Repetition codes • Parity codes • Cyclic codes See more As a linear subspace of $${\displaystyle \mathbb {F} _{q}^{n}}$$, the entire code C (which may be very large) may be represented as the span of a set of $${\displaystyle k}$$ codewords (known as a basis in linear algebra). These basis codewords are … See more 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 … See more 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 codewords is equal to d. In 1984 Arrigo … See more WebIn 1974 [39], Wyner suggested constructing the bins as cosets of a binary linear code and showed the optimality of this construction. More precisely, if the linear block code achieves the capacity of the binary symmetric channel (BSC) that models the correlation between the two sources, then this capacity-achieving channel code can be turned ...

WebA formula for the order of the automorphism group of a binary linear constant weight code in terms of its parameters is presented, which is a key step to determine more algebraic structures on constant weight codes with given parameters. We give a characterization for the binary linear constant weight codes by using the symmetric difference of the … WebIn mathematics and electronics engineering, a binary Golay code is a type of linear error-correcting code used in digital communications. The binary Golay code, along with the ternary Golay code, has a particularly deep and interesting connection to the theory of finite sporadic groups in mathematics.
