A user terminal transmits a preamble signal generated using a Zadoff-Chu sequence. A correlation processing unit 21 calculates autocorrelation of a received preamble signal. A preamble detection unit 22 detects a side peak position of the autocorrelation of the preamble signal and calculates the main correlation value representing correlation at the main peak position and the side correlation value representing correlation at the side peak position. A frequency offset estimation unit 24 estimates frequency offset that has occurred in the wireless transmission path according to the main correlation value and the side correlation value. |
