ABSTRACT:
A multicarrier transmission apparatus and multicarrier transmission method that achieve a desired transmission rate without arranging a plurality of transmission antennas apart from each other. A stream duplicating sections (140-1) duplicates stream #A by the same amount as the number of transmission antennas (2in this case) to output to an adding sections (160-1) and a delay section (152). A stream duplicating section (140-2) duplicates stream #B by the same amount as the number of transmission antennas (2in this case) to output to an adding section (160-1) and a delay section (154). The delay section (152) and the delay section (154) delay transmission timing of stream #A and that of stream #B by delay time decided by a delay time deciding section (158), respectively. At this time, the delay time of stream #A and that of stream #B decided by the delay time deciding section (158) are different from each other.
