WebOct 31, 2024 · Abstract: New optimum binary shortened cyclic codes with redundancy r = 32 and burst-error correction capability b are presented. The codes are found by performing an exhaustive computer search using the Kasami algorithm, and their performance is compared with analytical bounds by Reiger, Abramson and Campopiano. WebSep 23, 2024 · Binary Code- Weighted Code In this type of code, each digit/symbol position of the number signifies a specific weight. That is in weighted code, each decimal digit is expressed by a group of four bits and each bit has a weight of 8, 4, 2, 1. 23→ 2 3 ↓ ↓ Code→ 8+4+2+1 8+4+2+1 0+0+1+0 0+0+1+1

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 …
