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 23):
The apparatus of  claim 21 , wherein:\n the coarse acquisition code comprises a first encoded data rate corresponding to a first bit length and the navigation message code comprises a second encoded data rate corresponding to a second bit length, wherein the first encoded data rate is higher than the second encoded data rate such that the first bit length is shorter than the second bit length, and the navigation message code modulates the coarse acquisition code; a duration of the integration period is greater than the second bit length; the unpredictable bits comprise known bit values of the coarse acquisition code modulated by unknown bits of the navigation message code, and the predictable bits comprise known bit values of the coarse acquisition code modulated by known bits of the navigation message code; wherein the bit predictor is operative to predict values of data bits to be received in a second navigation message subsequent to the loss of connectivity to the assistance data based at least in part on the first duplicate navigation message; and the receiver is further operative to:\n demodulate first portions of the second navigation message comprising the predictable bits; \n coherently integrate the first portions, and \n initiate a holdover mode during at least one of receipt and processing of second portions of the second navigation message comprising the unpredictable bits.
