Abstract

A method and system using correlator circuitry in a GPS baseband circuit for despreading both GPS data and local wireless data. In one embodiment, an RF signal (local wireless) is received at a first frequency and a digital baseband signal is produced therefrom at a second frequency. A GPS signal is also received at the second frequency and a digital baseband signal is produced therefrom. Both baseband signals are provided to a single GPS baseband circuit for data recovery. In a GPS mode, GPS data is recovered form the baseband signal by despreading and demodulation. In a local wireless mode, the GPS baseband circuit is programmed to despread and recover local wireless data. The GPS data and the local wireless data can be stored in a data buffer for downstream processing. By sharing the correlator circuits in the GPS baseband circuit for both GPS data recovery and local wireless data recovery, a low cost receiver unit is provided. In one embodiment, the local wireless baseband signal is produced by up conversion of the local wireless RF signal and then processing though a common RF front-end circuit that is also used by the received GPS signal.
