A '''BCH (Bose, Ray-Chaudhuri, Hocquenghem) code''' is a much studied ''code'' within the study of [[coding theory]]. In technical terms it is multilevel, cyclic, [[error]]-correcting, variable-length [[digital]] [[code]] used to correct errorsmutiple uprandom toerror approximately 25% of the total number of digitspatterns.

BCH codes are not limited to [[Binary Code|binary]] codes, but may be used with multilevel [[phase-shift keying]] whenever the number of levels is a prime number or a power of a [[prime number]]. A BCH code in 11 levels has been used to represent the 10 decimal digits plus a sign [[numerical digit|digit]].
