PROBLEM TO BE SOLVED: To provide an OFDM diversity synchronizing/receiving device for efficient AGC of each reception system. SOLUTION: With an OFDM receiving device, a transmission path characteristics, signal level fluctuation, and frequency deviation quantity of in-coming wave are assumed, based on correlation detection information of the in-coming wave received in a plurality of reception systems and an FFT window position detection information, and using the assumption result, feedback is made for one VCO so that a common reference clock is generated for a plurality of reception systems. Further, the assumption result is used to generate a single AGC control information, for efficient AGC of a plurality of reception systems. |
