Abstract
An error control apparatus includes: a deinterleaver for deinterleaving data of a predetermined number of bits coded by predetermined cyclic codes, which is to be interleaved in accordance with a predetermined interleaving order; a first cyclic code checking circuit for receiving an output of the deinterleaver and making a cyclic code check on the data of the predetermined number of bits by a check system corresponding to a coding system of the cyclic code; and a second cyclic code checking circuit for receiving an output of the deinterleaver and making a cyclic code check on the data of the predetermined number of bits by a check system corresponding to the coding system of the cyclic code simultaneously with the cyclic code check by the first cyclic code checking circuit in substantially the same time while canceling an interleave effect by the deinterleaver.
