Abstract
Data of an input data series is written into a first interleaver. The data is read out column by column or row by row from the first interleaver and written into a plurality of second interleavers column by column or row by row. The data is read from each of the second interleavers and written into one or a plurality of third interleavers as necessary. The operation is repeated once or a plurality of times, thereby reading the data from each of the interleavers and generating a data series. Interleaving is carried out by generating interleaving patterns with a plurality of interleaving patterns. Further, an interleaving pattern suitable for turbo encoding or transmission is generated.
