A correlator(65) correlates the received signal with the generated training signal. A first peak detector(80) detects a correlation peak if a correlation value outputted by the correlator is bigger than a first threshold value. A second peak detector(90) multiplies correlation values of a first section before a correlation peak value outputted by the correlator by correlation values of a second section after the correlation peak value if the first peak detector detects the correlation peak value. After that, the second peak detector detects synchronization of the received signal from the multiplication result.
