<p><P>PROBLEM TO BE SOLVED: To provide an automatic frequency control device that prevents failure in reception even when limiting a frequency sweep range of receivers. <P>SOLUTION: The automatic frequency control device (control device 2) is used in a reception system including a plurality of receivers (1-1 to 1-n) for receiving a multi-carrier signal. The automatic frequency control device (control device 2) includes: monitoring means (oscillator 21 and frequency measurer 22) for monitoring respective frequencies of carriers distributed in the multi-carrier signal; and setting means (frequency measurer 22) for setting accurate center frequencies of the carriers to be received by the plurality of receivers (1-1 to 1-n) on the basis of the results of monitoring by the monitoring means (oscillator 21 and frequency measurer 22). <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
