Abstract: A system and method are disclosed that may allow for enhanced gain control for two radios. In an example method, a first radio may receive a wireless signal on a first frequency band, the wireless signal including at least a header and a payload. A first gain control operation may be performed based at least in part on information in the header of the wireless signal. A second radio may be determined to initiate a transmission on a second frequency coinciding with the first frequency band before reception of the wireless signal is completed, where the second radio is co-located with the first radio. A second gain control operation may be performed based at least in part on an expected interference associated with the transmission from the second radio, and one or more gain levels may be adjusted for reception of the wireless signal, based on the second gain control operation.

Abstract: Method, computer program product, and apparatus for signal tracking and decoding in GNSS are disclosed. In one exemplary implementation, a satellite receiver may be configured to receive a first sub-frame of a satellite signal. It defers a determination of validity of the first sub-frame until a preamble of a second sub-frame is received. The satellite receiver receives the preamble of the second sub-frame, and then determines whether there is a data decoding error of the first sub-frame using the first sub-frame and the preamble of the second sub-frame.

Abstract: A mobile device position determination method includes: determining a plurality of bandwidths of a pilot signal corresponding to different times at which the pilot signal is received by a mobile device from a base station, the plurality of bandwidths of the pilot signal including a first bandwidth corresponding to a first time at which the pilot signal is received and a second bandwidth corresponding to a second time at which the pilot signal is received, the second time being after the first time; filtering the pilot signal using the second bandwidth; determining a positioning parameter from the pilot signal filtered using the second bandwidth; and determining a position of the mobile device using the positioning parameter.
