“…From table 1 it is seen that the interchannel correlation increases, starting from channel 5. This suggests that the channels whose indices lie in the range [4][5][6][7][8][9][10][11] have a high correlation dependence, the maximum correlation value between channel 10 and 11. 0,23 0,3 0,56 0,89 1 0,95 0,95 0,95 0,95 0,92 0,92 0, 9 5 0,23 0,27 0,51 0,81 0,95 1 0,97 0,97 0,97 0,96 0,95 0,95 6 0,22 0,29 0,53 0,85 0,95 0,97 1 0,985 0,983 0,978 0,972 0,968 7 0,234 0,29 0,52 0,845 0,945 0,975 0,985 1 0,990 0,981 0,984 0,982 8 0,23 0,29 0,50 0,82 0,935 0,970 0,983 0,990 1 0,992 0,991 0,988 9 0,23 0,29 0,50 0,81 0,924 0,963 0,978 0,989 0,992 1 0,995 0,994 10 0,224 0,295 0,491 0,803 0,912 0,955 0,972 0,984 0,991 0,995 1 0,996 11 0,23 0,30 0,499 0,798 0,907 0,950 0,968 0,982 0,988 0,994 0,996 1 3.1 Based on the constructed correlation matrix, we construct the L tree of indicesthese are ordered pairs of channels (for example, channels numbered 10 and 11).…”
