Abstract

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.
