PROBLEM TO BE SOLVED: To enable satisfactory synchronizing operation, even when a high-level interference wave exists. SOLUTION: For a received signal to which subordinate synchronizing detection is performed, a correlative waveform signal with a desired wave synchronizing signal is computed from a memory 52 by a complex correlator 51. Further, for this received signal, a correlative waveform signal with an interference wave synchronizing signal from a memory 55 is computed by a complex correlator 54, these correlative waveform signals of desired wave and interference wave are synthesized by multiplying a weight coefficient, the interference wave component in the correlative waveform signal of desired wave is removed by an interference removing means 62 and corresponding to that synthesized output, synchronization is loaded to a synchronizing means. The weight coefficient is found by a method similar to a decorrelator as the interference removal technique of a time division multiple access (CDMA) system. |
