Title: Automatic frequency control circuit
Inventor: ASAHARA TAKASHI
IPC: H04L27/22
Filed: 1996-12-25
Abstract: PROBLEM TO BE SOLVED: To pull in a reception signal to a normal phase control point even if a frequency deviation exceeding a range where the reception signal can be pulled into the phase control point. SOLUTION: The signal from a phase difference detection part 12 is decoded by a code judgment part 20 and is inputted to a detection area judgment part 21. The detection area judgment part 21 detects the synchronous word pattern of a unique word which is periodically inserted into decoded data, and judges in which area the synchronous word pattern has been detected. When an acquisition judgment part 22 judges that the frequency is controlled at the erroneous phase control point, a frequency deviation control part 23 obtains the controlled variable of the frequency deviation, which corrects the detection area of the reception signal to become the area of the correct phase control point based on the detection area of the reception signal, and adds a value corresponding to the controlled variable to the output value of an averaging filter part 14.  Thus, frequency deviation quantity is corrected so that control is executed at the correct phase control point.
