An electronic device comprising: circuitry configured to assign a signal for synchronization acquisition to frequency components ref_F0 and ref_F1 to be supplied to a first IFFT unit for transmission over a first transmit antenna of the mobile terminal; assign a signal for synchronization acquisition to frequency component base_F2 to be supplied to a second IFFT unit for transmission over a second transmit antenna of the mobile terminal; digitize first baseband signal obtained from a high-frequency signal received via a first reception antenna, the first baseband signal received via the first reception antenna including the signals for synchronization acquisition assigned to frequency components ref_F0, ref_F1 and base _F2; digitize a second baseband signal obtained from a high-frequency signal received via a second reception antenna, the signals for synchronization acquisition assigned to frequency components ref_F0, ref_F1 and base F2; specify a position of a preamble included in the digitalized first and second baseband signal; calculate a square of the preamble; specify a peak from a value obtained by the square of the preamble; perform a fast Fourier transform on the digitized first and second baseband signal using a position of the peak as a start of an FFT window; extract phases of the frequency components ref_F0, ref_F1 and base_F2 for phase measurement from the digitized first and second baseband signal which has been subjected to the FFT; obtain a phase difference among the phases of the frequency components ref_F0, ref_F1 and base_F2; and obtain a phase correction value of a reception signal using the phase difference and a phase reference from each of the first and second baseband signals. circuitry configured to assign a signal for synchronization acquisition to frequency components ref_F0 and ref_F1 to be supplied to a first IFFT unit for transmission over a first transmit antenna of the mobile terminal; assign a signal for synchronization acquisition to frequency component base_F2 to be supplied to a second IFFT unit for transmission over a second transmit antenna of the mobile terminal; digitize first baseband signal obtained from a high-frequency signal received via a first reception antenna, the first baseband signal received via the first reception antenna including the signals for synchronization acquisition assigned to frequency components ref_F0, ref_F1 and base _F2; digitize a second baseband signal obtained from a high-frequency signal received via a second reception antenna, the signals for synchronization acquisition assigned to frequency components ref_F0, ref_F1 and base F2; specify a position of a preamble included in the digitalized first and second baseband signal; calculate a square of the preamble; specify a peak from a value obtained by the square of the preamble; perform a fast Fourier transform on the digitized first and second baseband signal using a position of the peak as a start of an FFT window; extract phases of the frequency components ref_F0, ref_F1 and base_F2 for phase measurement from the digitized first and second baseband signal which has been subjected to the FFT; obtain a phase difference among the phases of the frequency components ref_F0, ref_F1 and base_F2; and obtain a phase correction value of a reception signal using the phase difference and a phase reference from each of the first and second baseband signals.
