Title: ERROR CONTROL DEVICE AND METHOD USING CYCLIC CODE
Abstract:
An error control device including a de-interleaver (52) for de-interleaving data with a specified number of bits which has been coded by a preset cyclic code and is scheduled to be interleaved in a preset interleaving sequence, a first cyclic code inspection circuit (58) for performing a cyclic code inspection on the data with the specified number of bits using an inspection method in conformity with a cyclic code coding system on receiving an output from the de-interleaver (52), and a second cyclic code inspection circuit (60) for performing a cyclic code inspection on the data with the specified number of bits using an inspection method in conformity with a cyclic code coding system while canceling an interleaving effect by the de-interleaver concurrently with the cyclic code inspection by the first cyclic code inspection circuit and within a virtually identical time on receiving the output from the de-interleaver.
