Abstract
In a decoding system which decodes a transmitted signal encoded by using a Reed-Solomon code, an error locator polynomial of the nth iteration is calculated based on a predetermined number of syndrome values; a group of variables of the (n-1)st iteration including a discrepancy and an error locator polynomial thereof; and an error locator polynomial of the (n-2)nd iteration. The method for providing the error locator polynomial comprises the steps of calculating a discrepancy of the nth iteration based on the syndrome values and the error locator polynomial of the (n-1)st iteration; calculating a temporal term based on the discrepancy of the (n-1)st iteration and the error locator polynomial of the (n-2)nd iteration; determining a correction term based on the temporal term and the discrepancy of the nth iteration; and computing the error locator polynomial of the nth iteration based on the correction term and the error locator polynomial of the (n-1)st iteration.
