Abstract The object of this invention is to provide an interleaving method which includes receiving a data sequence having a plurality of blocks each having a length based on a prime number P; generating sequence permutation data by performing a given operation on elements of a Galois field of a characteristic P and permuting results of the given operation, so that sequence permutation data are generated; and permuting a sequence of data of the data sequence in accordance with the sequence permutation data.
