摘要：
A transmitting equipment is used in a mobile communication system in which a signal obtained by cyclically shifting a predetermined sequence is used for communication. An inverse fast Fourier transform device of the transmitting equipment converts a signal obtained by signal processing on a predetermined sequence in a frequency region into a time region by inverse fast Fourier transform. A cyclic shift device cyclically shifts by a predetermined amount of shift the sequence in the signal converted into the time region by the inverse fast Fourier transform device.
