Abstract
A method for correlating using an N-dimensional accumulator to test 2alignments. The method comprises transmitting a spread code comprising a data sequence and a pseudo-noise sequence; receiving, at a plurality of successive clock cycles, the spread code further comprising a plurality of alignments; assigning each of the plurality of alignments to an alignment vector comprising 'N' dimensions; generating a binary representation of each of the plurality of alignments in the alignment vector, wherein 1 and −1 to depict the logic states 0 and 1 with the DS-CDMA signal that has been received by the receiver; accumulating a plurality of moving averages for each dimension of the N-dimensional alignment vector; determining an absolute value of each moving average; combining each of the plurality of moving averages with each corresponding alignment vectors; identifying when the sign of each dimension of the accumulation vector becomes stable; and determining the alignment vector.
