WebMay 25, 2024 · 1 Answer. For instance ( x + 1) ( x + 2) is a cyclic code over GF ( 3) of length 6 and dimension 4. In fact, all cyclic codes of length n over GF ( q) are given by the following procedure. Let. be the irreducible factorization of x n − 1 over GF ( q). If C is cyclic code of length n then C = g ( x) where g is a combination of g i l i s. WebJan 30, 2024 · Nguyen et al. proved that one can obtain a cyclic binary constant-weight code from a p-ary linear cyclic code, where p is a prime, by using a representation of GF(p) as cyclic shifts of a binary p-tuple. Two correspondingly optimal classes of CPCs were constructed by appropriate selection of codewords from the cyclic binary constant …
