A window setup unit(210) sets a window with a certain width in the processed phase reference symbol signal. A power calculating unit(220) calculates powers of signals in the set window. A null interval deciding unit(230) decides a window interval having the minimum power among the powers calculated in the power calculating unit(220), and decides a null interval in which data information does not exist in the phase reference symbol signal. A frequency estimating unit(240) estimates the frequency synchronization of the received signal to an end point of the null interval decided in the null interval deciding unit(230).
