PROBLEM TO BE SOLVED: To provide a receiving technique of an OFDM wireless signal wherein precise synchronization process can be performed. SOLUTION: A receiver is configured so that the maximum carrier frequency error and the maximum Doppler frequency are not larger than a half of a sampling frequency in the receiver, wherein the complement of synchronization is attained on the basis of: a reception signal including an OFDM symbol in which at least a synchronization channel is arranged and an OFDM symbol in which an identification channel is arranged; a synchronization channel replica signal which is an OFDM symbol in which only the synchronization channel is arranged; and an identification channel replica signal which is an OFDM symbol in which only the identification channel is arranged. Following of synchronization is attained on the basis of: a reception signal including an OFDM symbol in which a reference signal is arranged to at least a plurality of sub-carriers; and a reference replica signal being the OFDM symbol in which only the reference signal is arranged.
