Abstract
A method and system are disclosed for blind decoding of Bluetooth packets. According to one aspect, a method of decoding packets includes detecting a packet using blind LAP detection. The method also includes estimating a duration of a payload of the packet and decoding a payload of the packet over the estimated duration according to each of a plurality of forward error correction (FEC) coding rates to produce a packet header. For each of a plurality of de-whitening seeds, the method includes performing de-whitening, extraction and reverse decoding on the packet header to produce a plurality of candidate upper address parts (UAPs). The method includes obtaining a subset of the candidate UAPs, each candidate UAP having a corresponding CRC code, and forming an ordered list of candidate packet types based at least in part on the estimated duration. The method includes performing a CRC to select a UAP.
