Abstract:Abstract-Somenew examples of binary Bose-ChaudhuriHoquengkn (BCH) codes of length 255 are found for which tbe minimum distance and designed dishace agree.For a cyclic code of length n with generating polynomial g(x), the designed distance S is defined as follows: 6-1 is the maximum length of a string of consecutive powers of a which are zeros of g (x), where a is a primitive nth root of unity. It is known (see e.g. [l, p. 2011) that S is a lower bound on the true minimum distance d. For most Bose-Chaudhuri-Hoc… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
