Abstract:
1. A Bluetooth receiver, comprising: a RF front end configured to receive a Bluetooth signal including a preamble and 34-bit pseudo-number (PN); a DC estimator communicatively coupled to the RF front end; a frame synchronizer communicatively coupled to the DC estimator; wherein the DC estimator is configured to perform DC offset estimation by determining an average value of samples of the preamble and the frame synchronizer is configured to use the 34-bit PN for frame synchronization; a Frequency Shift Keying (FSK) demodulator communicatively coupled to the frame synchronizer; an equalizer communicatively coupled to the FSK demodulator; wherein the Bluetooth signal further includes a Local Area Network (LAN) access profile and the equalizer includes a channel estimator configured to use the LAN access profile for channel estimation.
