TRANSMITTER, RECEIVER, TRANSMISSION METHOD, AND RECEPTION METHOD

摘要

PROBLEM TO BE SOLVED: To make it possible to simply and accurately detect the peak of a periodic auto-correlation value.

SOLUTION: A transmitter in a mobile communication system includes: a basic signal sequence generation unit which generates a basic signal sequence; a secondary signal sequence generation unit which generates a secondary signal sequence equal to a sequence about which the basic signal sequence is cyclically shifted by a specified frequency shift amount in a frequency domain and by a specified time shift amount in a time domain; a signal generation unit which generates a signal including the secondary signal sequence but not including the basic signal sequence; an IFFT unit which performs inverse Fourier transformation on the generated signal; and a transmission unit which transmits a transmission signal including output from the IFFT unit.
