Abstract
A frame synchronization apparatus and method for controlling a frame synchronization process. The frame synchronization apparatus includes a correlation-value computation section; an IQ component select section; and a synchronization-signal outputting section. The correlation-value computation section computes a correlation value representing a correlation between a known delay wave detection series and a received delay wave detection series. The IQ component select selects a larger one of absolute values representing the amplitudes of I and Q. The synchronization-signal outputting section carries out a peak detection process to detect a peak in pieces of data arranged along a time axis to form a correlation-value series and output a frame synchronization signal for said input signal in accordance with a result of said peak detection process.
