A METHOD OF ACQUIRING A RECEIVED SPREAD SPECTRUM SIGNAL

摘要

A method of acquiring a received spread spectrum signal comprises receiving a spread spectrum signal, analyzing the received signal to detect interference within the received signal, and adapting the baseband processing of the received signal to reduce power consumption during periods of detected interference. This allows the GPS processing resources to be focussed on areas of signal where there is little or no interference, and this is possible without modification to the source of interference. The interference is detected from an analysis of the received signal, and in particular before the baseband digital signal processing.
