Timing phase information is extracted from a power spectrum of a received signal whose amplitude is modulated per frame or sub-frame, and timing phase synchronization of the received signal is performed with the timing phase information. Also, a vector signal of the power spectrum is generated, the vector signal is multiplied by another vector signal to be rotated, a sign decision of the rotated vector signal is performed, a result of the sign decision is integrated to be outputted as the timing phase information, and a vector conversion is performed to the integrated value to be fed back as the other vector signal. |
