1. A transmitter comprising:
a generation unit configured to generate multiple OFDM symbols included in a predefined time unit; and a transmitting unit configured to transmit the multiple OFDM symbols generated at the generation unit, wherein the generation unit arranges a primary synchronization channel at an end OFDM symbol in the predefined time unit, the primary synchronization channel being generated based on one sequence, and a secondary synchronization channel, where two types of sequences are alternately arranged in a frequency domain, at an OFDM symbol preceding the OFDM symbol where the primary synchronization channel is arranged, and a cyclic prefix is arranged for each of the multiple OFDM symbols, and any of specified different cyclic prefix lengths is used.
