  • Frequency error detector
    Patent number: 5991342
    Abstract: A frequency error detector which is independent of channel distortion and determines in a receiver the frequency deviation between the carrier frequency generated in the receiver and the carrier frequency of a received signal has a first differential power meter that forms the power difference between spectral components that are symmetrical with the receiver carrier frequency and belong to the received signal spectrum, and it has a second differential power meter that forms the power difference between spectral components that are symmetrical with the receiver carrier frequency and belong to the spectrum formed by undersampling of the received signal. The sum of the output signals of the two differential power meters provides information on the frequency deviation.
