METHOD AND APPARATUS FOR AUTOMATIC FREQUENCY CORRECTION WITH A FREQUENCY ERROR SIGNAL GENERATED BY BLOCK CORRELATION OF BASEBAND SAMPLES WITH A KNOWN CODE SEQUENCE |
摘要 |
The present invention is related to a method and apparatus for automatic frequency correction of a local oscillator. The apparatus receives a carrier signal. The carrier signal includes a code sequence known to the apparatus. The apparatus downconverts the carrier signal to a baseband signal using the local oscillator. The apparatus performs a block correlation of the samples of the baseband signal with the known code sequence to generate a frequency error signal. The frequency error signal is fed back to the local oscillator to correct the frequency error.
