Abstract:
The present disclosure is directed to utilities (methods, systems, apparatuses) associated with improving the signal-to-noise ratio of a wireless signal at a receiver. It is known in the art to correlate a received signal with a replica signal generated at the receiver to improve reception. However, the inventors have determined that correlation using a replica signal which is not completely accurate may be detrimental. An improved method of correlation disclosed herein includes identifying data bits which are predictable and performing correlation with respect to those data bits while ignoring data bits which are identified as unpredictable. This method may have particular advantages in the case of receivers having attenuated reception (e.g., indoors) after losing a data connection used for receipt of assistance data.

Claim (Index 7):
The method of  claim 6 , wherein the unpredictable bits comprise ephemeris information updated by a control segment to at least one satellite vehicle of the global navigation by satellite system subsequent to receipt of assistance data comprising a first duplicate navigation message at the receiver via a data network connection, the first duplicate navigation message identifying values of data bits in a first navigation message of the broadcast positioning system signal.
