Abstract
Embodiments of a wireless communication device and a method for reducing in-band interference in a positioning system receiver are generally described herein. Other embodiments may be described and claimed. In some embodiments, an adaptive filter may be used to measure interference from signals generated from coupled signals of a co-located transmitter. The interference may be subtracted from digital positioning system signals provided by the positioning system receiver. In some embodiments, the interference is not subtracted from the positioning system signals when the transmitter is not active.
Claims29
Interference reduction circuitry comprising:
- a signal path to generate signals representing interference from transmissions of a co-located transmitter;
- and
- circuitry to remove the measured interference from received digital positioning system signals.
A wireless communication device comprising:
- positioning system receiver circuitry to generate digital positioning system signals;
- a co-located transmitter for transmitting communication signals;
- and
- interference reduction circuitry to subtract signals representing interference from the digital positioning system signals caused by transmissions from the co-located transmitter.
A method comprising:
- generating signals representing interference from coupled signals of a co-located transmitter;
- subtracting the signals representing interference from digital positioning system signals;
- and
- refraining from performing the generating and subtracting when the co-located transmitter is not active.
An integrated circuit comprising:
- positioning system receiver circuitry to generate digital positioning system signals;
- a co-located transmitter for transmitting communication signals;
- and
- interference reduction circuitry to subtract signals representing interference from the digital positioning system signals caused by transmissions from the co-located transmitter.
