    Abstract: A method (200) and apparatus (900) for correcting frequency errors of received signals in a wireless communication receiver are disclosed. The wireless communication device (900) receives (204) a signal; correlates (206) the received signal with the plurality of offset prestored data sets; generates (208) at a predetermined data rate interval a plurality of signal correlations where each of the plurality of correlations is correlated to each of the plurality of offset prestored data sets; and computes (210) a frequency error estimate based upon the plurality of signal correlations.

    Abstract: A reconfigurable downconverter (10) for a multi-band positioning receiver is operable with an RF synthesizer (18) with fixed output frequency, and a fixed wideband RF input (28). The downconverter (10) includes an RF mixer (12) operable to accept a range of frequencies that encompass the GPS and Galileo frequency bands and to output a downconverted IF signal (32). A fixed frequency local oscillator signal (34) is coupled to the RF mixer (12). At least one IF processor 14 further downconverts the downconverted IF signal (32) to at least one baseband signal (22). At least one of the IF processors (14) is reconfigurable for different frequency bands.

    Abstract: A method for locating a satellite positioning system receiver, for example, a satellite positioning system enabled wireless communications device in cellular network, including obtaining a coarse position and/or a time estimate (210), and computing a satellite positioning system based position and/or time solution (240) that is constrained by uncertainty information associated with the coarse position and/or a time estimate. The uncertainty constraints may also be used to identify erroneous measurements used to compute the position solution.
