Abstract:
A wireless mobile terminal for a wireless communications system, comprising:a wireless transceiver; anda global positioning system (GPS) receiver that shares a reference oscillator signal with said wireless transceiver, comprising:a multiplier that multiplies the reference oscillator signal by a first integer to produce a first GPS local oscillator signal;a first mixer that is responsive to the first GPS local oscillator signal and a GPS satellite signal and generates a first output signal having an intermediate frequency;a first divider that divides the reference oscillator signal by a second integer to produce a second GPS local oscillator signal;a second mixer that is responsive to the first output signal and the second GPS local oscillator signal and generates a second output signal used by the GPS receiver for signal processing; anda second divider that divides the reference oscillator signal by a third integer to produce a third GPS local oscillator signal used in signal processing by the GPS receiver.
