Abstract

In a Global Positioning Satellite receiver, the method comprising: receiving an input signal having a signal carrier frequency; generating a local oscillator signal having frequency which is offset from the carrier frequency; mixing the input signal with the local oscillator signal to produce an intermediate frequency signal; converting the intermediate frequency signal to a multiple-sample digital representation; generating a multiple-sample digital representation of a replica signal; and correlating the multiple-sample digital representation of the intermediate frequency signal with the multiple-sample digital representation of the replica signal; in which the local oscillator frequency offset being sufficient such that harmonics of the digital representation of the replica signal fall above the highest intermediate frequency.
