Abstract
Method and apparatus for a wireless receiver are described which derive at least a first stream of first digitized samples from a received analog signal at a first sampling rate and identify a first frequency offset based on a plurality of parallel correlations using complex reference signals which differ from each other by phase offsets. A second frequency offset is identified based on tracking a demodulation accuracy for each symbol which is demodulated from the first stream of digitized samples. These frequency offsets can be used to rotate decision areas in the demodulator. The methods and apparatus may be used in a Bluetooth receiver.
