BLUETOOTH SIGNAL RECEIVING METHOD AND DEVICE USING IMPROVED CARRIER FREQUENCY OFFSET COMPENSATION

摘要

The present invention relates to a method of carrier frequency offset acquisition and tracking for a Bluetooth Smart receiver. The Bluetooth receiver of the present invention generates a frequency-proportional signal having a value proportional to the frequency of the baseband signal by generating a baseband signal by performing frequency-shift demodulation on the received signal, Generates a plurality of series of bit streams separated by the training bit stream, determines whether a plurality of series of bit streams satisfies a training bit string condition, and when the plurality of series of bit strings satisfy the training bit string condition And the measured error measure is reflected in the frequency proportional signal as an effective error measure.;
