Detection and reduction of periodic jamming signals in GPS receivers and methods therefor

摘要

A method for eliminating or reducing interference in a receiver, for example, interference in a satellite positioning system receiver caused by a co-located TDMA transmitter, including detecting (210) the presence of a jamming signal, generating a synchronous blanking signal (220), and reducing the jamming signal by blanking (230) the receiver with a blanking signal. In one embodiment, the jamming signal is detected in the receiver, for example, at a correlator output of a satellite positioning system receiver.
