Abstract:
1. One or more non-transitory computer-readable media storing computer-executable instructions that, when executed, cause one or more processors to perform acts comprising: receiving signals s from N sensors s calculating, using a first type of correlation, N−1 correlation sequences E{s calculating an independent data set by finding a total of (N−1)×M independent delays (l) with associated correlation values (R) where l confirming, using a second type of correlation, Mi largest peaks found using the first type of correlation, the second type of correlation being direct correlation; retaining M largest peaks of the correlation sequences confirmed using the second type of correlation, where M is a parameter and Mi>M; determining a valid solution from a set of tentative solutions comprising N−1 delay values with an ith delay value (i=1 to N−1) drawn from one of the M calculating correlation sequences extracting a dependent data set comprising selecting a solution.
