Abstract
In an interleaving circuit, writing and reading are executed on the two dimonsional array memory according to a first address sequence and a second address sequence, and product code errors occurring on the same column are propagated to the columns which are different with each other. The errors are thereby scattered to minimize the decreasing of the error correcting capability of the product codes.
