Abstract
An interleaving method including the step of (1) receiving a data sequence having a plurality of blocks, each having a length based on a prime number P; (2) generating sequence permutation data by performing a given operation on elements of a Galois field of a characteristic P; (3) permuting results of the given operation, so that sequence permutation data are generated; and (4) permuting a sequence of data of the data sequence in accordance with the sequence permutation data.
