Abstract
Apparatuses are described and disclosed which operate in a first mode to receive non-position signals, for example FM radio signals, and in a second mode of operation to receive land-based position signals, for example LORAN signals.
Claims25
An apparatus, comprising:
- a wireless signal receiver frontend,
- a digital non-position signal processing portion,
- a digital position signal processing portion, and
- switching circuitry configured to couple an output of said frontend with an input of said digital non-position signal processing portion in a first mode of operation and to couple the output of the frontend with the digital position signal processing portion in a second mode of operation,
- wherein the wireless signal receiver frontend includes at least amplifying circuitry used both in the first mode of operation and in the second mode of operation of the frontend.
2 more elements
An apparatus, comprising:
- an amplifier,
- a mixer, a first input of said mixer being coupled with an output of said amplifier, and
- a local oscillator,
- wherein the apparatus is operable in a first mode to receive non-position signals and in a second mode to receive land-based position signals,
- wherein in said first mode said local oscillator is coupled with a second input of said mixer, and
- wherein in said second mode a constant signal is coupled with said second input of said mixer.
3 more elements
A method, comprising:
- providing a wireless communication frontend including at least a mixer,
- providing a wireless communication digital portion,
- providing a position signal processing digital portion,
- setting the wireless communication frontend to a wireless communication mode,
- coupling the wireless communication frontend to the wireless communication portion,
- setting the wireless communication frontend to a land-based position signal mode, and
- coupling the wireless communication frontend to the digital position signal processing portion.
