METHOD AND APPARATUS FOR SPREAD SPECTRUM SIGNAL ACQUISITION

摘要

The present invention provides for a method of acquiring direct sequence spread spectrum signals and in particular, GPS signals, including the steps of obtaining an integration result by avoiding integration over bit edges, and includes the steps of splitting the received signal (A) into a plurality of signal chunks alternatively across a respective plurality of channels (B,C), each channel being arranged to carry a series of signal chunks, the division being controlled in a timed manner responsive to the signal bit period so that the signal chunks of one of the series signals do not include bit edges.
