Provided are a multicarrier transmitter and a multicarrier receiver which accelerate cell search and reduce a circuit scale by reducing the operation quantity for cell search. The transmitter (100) has: a real number SCH series generation part (105) which generates a real number series consisting of only real number signals; an SCH multiplexing part (104) which maps the real number series as a P-SCH; and an IFFT part (106) which converts a frequency signal to a time signal. By doing like this, the transmitter (100) forms a time-synchronous P-SCH, and performs transmission. Thus, a correlation operation quantity about the P-SCH on a reception side is reduced. |
