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 12):
The method of  claim 10 , wherein the predicting comprises:\n extracting, from the first duplicate navigation message, known values of data bits which are expected to remain unchanged in subsequent navigation messages including at least the second navigation message; extracting, from the first duplicate navigation message, known values of data bits which are expected to change in accordance with absolute time such that corresponding data bits in the second navigation message are predictable based upon time and the known values of the data bits of the first duplicate navigation message; and predicting a value of at least one data bit to be received from the global navigation by satellite system in the second navigation message based upon a known time and a value of a corresponding data bit observed in the first duplicate navigation message.
