Abstract
An interleave apparatus and an interleave method for preventing an increase in the number of retransmissions to improve the throughput. In a wireless communication apparatus having the interleave apparatus, a data holding part () two-dimensionally arranges and holds bit sequences. A first index calculating part () sequentially calculates first indexes to be used for reading, in a column direction, the bit sequences arranged in a row direction. A second index calculating part () sequentially calculates second indexes to be used for reversing the order of the upper-order and lower-order bits to be read from the even-numbered columns when the bit sequences are read in accordance with the first indexes. A third index calculating part () sequentially calculates third indexes to be used for reading the bit sequences from a different start position in accordance with the number of retransmissions. A reading part () reads the bit sequences in the order that is in accordance with the third indexes. A mapping part () maps the read bit sequences to the respectively corresponding subcarriers.
