Claim 13:
14. A Bluetooth receiver, comprising:
an antenna;
a memory configured for storing one or more modules; and
a processor configured for executing the modules to perform:
receiving audio data including a plurality of data packets;
transforming the audio data in a time domain to a frequency domain, wherein spectrum of the audio data is divided into a plurality of bands;
determining incorrect data packets among n consecutive data packets and average energy in each of frequency bands in the frequency domain, wherein spectrum of the incorrect data packets is divided into a plurality of bands the frequency bands are classified as a plurality of first bins and second bins based on the determined average energy in each of the frequency bands
taking the average energy in each of the first bins for the correct data packets as energy of the second bins for the incorrect data packets; and
recovering data in the first bins by a first predefined algorithm, and recovering data in the second set of frequency bins by a second predefined algorithm, wherein the second predefined algorithm.
