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 15):
An apparatus for continued tracking of a broadcast positional system signal upon loss of connectivity to assistance data regarding the broadcast positional system signal, comprising:\n a network adapter providing the apparatus with access to assistance data available via a network connection; a receiver operative to receive a broadcast positioning system signal comprising encoded data bits, the encoded data bits comprising predictable bits and unpredictable bits; a bit predictor operative to determine which of the encoded data bits are predictable based upon a structure of the encoded data bits defined in positioning system signal information available in the absence of connectivity to the assistance data and predict a phase of each of the predictable bits; and an integration module operative to integrate the encoded data bits over an integration period, wherein the unpredictable bits of the encoded data bits are not summed and the predictable bits of the encoded data bits are summed.
