Title: Automatic frequency control system
Inventor: SATO TORU
IPC: H04J11/00
Filed: 1997-01-17
Abstract: PROBLEM TO BE SOLVED: To prevent the decline of an information transmission capacity or the like and to use a relatively inexpensive frequency signal generator in the automatic frequency control system of reproduction carrier waves or local signals for frequency conversion on the side of the receiver of an OFDM (orthogonal frequency division multiplex) system. SOLUTION: Specified carrier level detectors 3 and 4 are respectively set so as to extract only the carrier waves of highest and lowest frequencies for instance among the carrier waves of OFDM modulation waves and detect and output the average level. By a level comparator 5, the levels of the respective detection output are compared and a control voltage corresponding to a level difference is outputted to a local signal generator 6. When a reception carrier wave frequency is shifted, the output of the comparator 5 is changed and the frequency of the local generator 6 is controlled by the output. The output of the level comparator 5 is turned to error signals and the detection frequency of the carrier level detector is adjusted. As the two specified carrier level detectors, synchronization detectors are used for instance.
