<p>A correlator may correlate a satellite signal modulated with a pseudo-random binary sequence with a local binary sequence including a given number of samples. The correlation may be performed on a given input sequence of length 2N−1 with respect to versions of the local binary sequence of length N having different phases and defining a search space for the correlation results of the table, organized in a table, wherein the lines of the table may represent the versions of the local binary sequence with different phases. The correlator may be structured to perform the correlation operating on a number N of samples equal to a sub-multiple of the number of samples included in the local binary sequence, by exploring the table according to rhomboidal subsets by operating on subsequent lines with sliding windows having widths equal to N and according to a lexicographical order with a periodic return to a new line.</p> |
