Abstract
A demodulator for a Bluetooth receiver includes an oversampling module configured to oversample input symbols a first plurality of times to generate a first plurality of oversampled input symbols. A correlating module is configured to correlate a second plurality of adjacent samples of the first plurality of oversampled input symbols with corresponding symbols in a predetermined enhanced data rate (EDR) sync word. Based on the correlation, the correlating module is configured to selectively generate a sync signal indicating that EDR sync has occurred. The second plurality of adjacent samples comprises more samples than one and less than all of the first plurality of oversampled input symbols.
