摘要：A method of performing a discrete Fourier transform (DFT) on one or moredata samples in a global navigation satellite system baseband tracking channel is

provided. The method comprises loading a pseudorandom noise code generator with aconstant value in the baseband tracking channel; setting a tracking loop integration timeaccording to a selected frequency resolution; updating a carrier generator with aselected DFT frequency in the baseband tracking channel; integrating a data sample inthe baseband tracking channel; and storing the integrated data sample in a DFT bin. Themethod determines whether all DFT bins have been received, and if all DFT bins have notbeen received, the method repeats starting with updating the carrier generator, until allDFT bins have been received.
