Title: Automatic frequency control system
Inventor: MISHIRO TOKIHIRO
IPC: H04L27/227
Filed: 1984-04-16
Abstract: PURPOSE:To omit a pilot signal and the reproduction of a carrier wave and to attain the automatic frequency control by using a frequency discrimination output signal obtained with the identification timing of a PSK (phase shift keying) signal to control a reception local oscillator. CONSTITUTION:The reception PSK signal sent from an input terminal 31 is mixed with the output signal of a voltage controlled oscillator 37 by a frequency converter 32. This mixed signal is converted into an intermediate frequency, for example, and applied to a demodulator through an output terminal 33. The PSK signal underwent the conversion of frequency through the converter 32 is applied to a frequency discriminator 34. The discriminator 34 has the linear wave detection sensitivity over an occupied band width of the PSK signal, and the frequency discrimination output signal is supplied to a switch circuit 35. The circuit 35 is turned on and off by a clock signal, and the output signal of the circuit 35 is used to the control voltage of the oscillator 37 via an LPF36. Then the oscillator 37 is controlled so that the frequency converted by the converter 32 is set at a fixed level.
