Abstract:
1. A multicarrier transmitting apparatus that performs radio communication by combining a multicarrier modulation method with a code division multiple access method, the multicarrier transmitting apparatus comprising: a multicarrier signal forming section that forms a multicarrier signal including a pilot signal and a scrambling code group identification code for identifying a group of scrambling codes divided into groups beforehand; and a transmission section that transmits the multicarrier-signal formed in the multicarrier signal forming section, wherein: in the multicarrier signal formed in the multicarrier signal forming section, the pilot signal is mapped in a frequency direction at predetermined time intervals and the scrambling code group identification code having a shorter time length than the predetermined time intervals is mapped in a time direction, such that an overlapping proportion of the pilot signal and the scrambling code group identification code is minimized.
