I got a problem with correlating 2 signals x1,x2 (isgnal in time) with missing data.
the missing data is periodic and is in both signals.
my problem is that the missing data is on few samples one after the other (for example 10 good samples 5 MD, 10 good samples, etc...)

when I perform correlation of the 2 signals, the correlation function got "waviness".

what are the ways to handle MD in correlation with my MD type?
