Abstract
Delay circuits 409 and 410 delay a digital baseband signal received by one symbol. Complex multiplier 411 performs a complex multiplication using the received digital baseband signal and the signal delayed by delay circuits 409 and 410. Of the multiplication result of complex multiplier 411, second accumulator 412 outputs the value resulting from an accumulation of the multiplication result of the phase reference symbol in the received digital baseband signal and that of the last half of the synchronization symbol in the delayed signal to frequency offset detector 413.
