Abstract: A method is provided for correlating signals. The method includes receiving a plurality of data vectors representing a plurality of signals. The method further includes determining, for each of the data vectors, a first set of correlation coefficients, where each of the correlation coefficients in the first set is based on a direct cross-correlation between each of the data vectors. The method further includes calculating an average of the first set of correlation coefficients, and determining, for each of the data vectors, a second set of correlation coefficients, where each of the correlation coefficients in the second set are based on an indirect cross-correlation between each of the data vectors and the average of the first set of correlation coefficients. The method further includes detecting a correlation between at least two of the data vectors based on the second set of correlation coefficients.
