A multicarrier transmitting apparatus capable of providing a fast cell search. A base station apparatus (100), which serves as a multicarrier transmitting apparatus for transmitting frames each including, as synchronization channel sequences, first synchronization sequences (P-SCH sequence) used for timing determinations and second synchronization sequences (S-SCH sequence) different from the first synchronization sequences, comprises a frame forming part (130) that forms frames each including the first synchronization sequence (P-SCH sequence) disposed in each of subcarriers symmetrical with respect to a DC component subcarrier (DC subcarrier) in the frequency direction; and an RF transmitting part (160) that transmits the frames. In this way, a frame receiving end can use a filter having a polarly symmetrical pass-band and needs no frequency shifting process, with the result that the processing amount at the receiving end can be reduced and hence a fast cell search can be achieved. |
