ABSTRACT:
A device and method for improving the signal to noise ratio by means of complementary sequences, consisting of the use of M complementary sets of sequences, understanding complementary as the sums of their autocorrelations, resulting in a Krönecker delta, the M value coinciding with the number of complementary sets of sequences which are orthogonal to one another, understanding by orthogonal that the sum of the cross-correlations of the complementary sequences of each set is zero.
