Abstract
Methods, systems, computer-readable media, and apparatuses for isolating a desired GNSS signal from a plurality of GNSS signals with the same code are presented. In some embodiments, a method may comprise receiving, by a mobile device, the plurality of GNSS signals, wherein the plurality of GNSS signals include the desired GNSS signal. Subsequently, the method may comprise processing the received plurality of GNSS signals to a down-converted signal, wherein the down-converted signal has a lower frequency than the desired GNSS signal, and wherein the down-converted signal includes a first channel associated with a non-zero frequency. Moreover, the method may comprise processing the down-converted signal to offset the first channel by an offset frequency corresponding to a fraction of the first channel to create an offset down-converted signal. Furthermore, the method may comprise determining the desired GNSS signal from the offset down-converted signal based on the offset frequency.
