To improve the frequency diversity effect by preventing the related bits in the encoded data from being biased to the specified carrier in the case of performing the multicarrier operation. A modulated symbol sequence is segmented in a data segmentation section (116), and the segmented modulated symbol blocks are mapped on a plurality of carriers in a segment mapping section (120). The data segmentation section (116) groups each of K parts in the modulated symbol sequence into the same number of N groups, cyclically shifts the N groups for the respective parts of any (K-1) parts with shift amounts which differ among the parts, and substitutes the cyclically-shifted groups of the plurality of parts in the modulated symbol sequence with one another among the parts to segment the groups into a plurality of blocks. |
