Abstract:
A method for acquisition of a received message including at least a portion encoded by an identifiable incoming code sequence, said method comprising the steps of:generating a plurality of different phases of said code sequence; summing together a plurality of said code sequences of different phases, to produce summed code signals; correlating said incoming code sequence with said summed code signals, to thereby generate a cross-correlation signal which indicates the presence of the desired phase of said code sequences among those phases in said summed code signals; if said cross-correlation signal indicates that said desired phase is among those phases in said summed code signals, performing individual cross-correlations between said incoming code sequence and those of said phases of said code sequence which make up said summed code signals, to thereby identify that one of said different phases of said code sequence by which said message should be decoded.
