INTERLEAVING PROCESSING APPARATUS

PROBLEM TO BE SOLVED: To reduce a processing quantity by controlling an increase in the number of times of interleaving processing regardless of the number of physical channels. SOLUTION: When HARQ data are 16 QAM data, the physical channels #0 to #14 are arrayed in memories 1 and 2 to a row direction and written so that a bit string of each physical channel is arrayed in a column direction, and the bit string comprised of one bit of each physical channel of #0 to #14 in the order of columns is read by column replacement portions 3 and 4. A read bit string is written in a different column from the memories 1 and 2 in memories 5 and 6 by the column replacement portions 3 and 4 according to an interleaving pattern in a table 7. The bit string of the column direction in the physical channels #0 to #14 in the memories 5 and 6 is different from a bit string in the memories 1 and 2 and the interleaving processing is conducted at each physical channel. When the HARQ data are the QPSK data, the memories 1 and 5 are used. COPYRIGHT: (C)2007,JPO&INPIT
