APPARATUS AND METHOD FOR DECODING USING VARIABLE ERROR-CORRECTING VALUE
摘要
A decoding apparatus and a decoding device are provided to obtain the optimum decoding performance in a low code rate by performing the decoding by using a variable correction value every iteration decoding in a check node update process. An initial normalizing constant and a normalizing constant correction value are set up(301). A check node is initially updated by using an initial normalizing constant(302). When updating the check node again, the update is performed by using the variable correction value adding the normalizing constant correction value to the initial normalizing constant(303). The update is performed by adding the normalizing constant correction value to the variable correction value applied to the prior update every an additional update(304).
