Abstract
Official abstract text for this publication.
A technique for reducing interference in a GPS-equipped wireless device having a transmitter is provided. In doing so, a GPS signal is acquired, and it is determined whether the GPS signal contains valid GPS data, the GPS signal having a GPS frequency range. If the GPS data is not valid due to the noted second harmonic interference, the transmit power levels of the transmitter within different categories of frequency blocks (frequency blocks corresponding to the second harmonic of the transmit frequency of the device interfering with the GPS frequency range entirely, partially and only slightly) are selectively and iteratively determined. The power levels in these frequency blocks are iteratively and selectively reduced to help determine valid GPS data.
First claim
Opening claim text (preview).
We claim: 1. A method of reducing interference in a GPS-equipped wireless device having a transmitter, the method comprising: acquiring a GPS signal containing GPS data, the GPS signal having a GPS frequency range; decoding the GPS data; determining whether the GPS data is valid; when the GPS data is not valid due to interference— first determining a transmit power level of the transmitter within a first plurality of frequency blocks that fall entirely within the GPS frequ…
