Abstract
A system for despreading a spread spectrum signal includes at least one receiver for capturing a plurality of snapshots of the signal and a processing device for constructing a confidence vector from at least two of the plurality of snapshots. The processing device is operable to generate a first estimated spreading sequence of the signal, and to correlate the first estimated spreading sequence and the confidence vector to generate a second spreading sequence for despreading the signal.
