Patent ID: 8824606

Claim:
A method comprising: receiving, at a first communication device, a radio frequency (RF) signal comprising a packet from a second communication device; at each access address decoding chain of a first access address decoding chain and a second access address decoding chain of the first communication device, applying a first frequency offset associated with the access address decoding chain to a phase difference signal determined from the RF signal, correlating the phase difference signal with a predetermined access address associated with the first communication device to yield a correlation result, wherein the correlating comprises comparing each symbol of the phase difference signal against a corresponding symbol of the predetermined access address and determining a number of matching symbols; determining that the correlation result associated with the first access address decoding chain exceeds the a correlation threshold; and demodulating the packet based, at least in part, on the phase difference signal after applying the first frequency offset associated with the first access address decoding chain.
