I have a reference time series and main data set(Similar sampling rate) which contains multiple instance of reference signal. Applying Cross Correlation (xcorr - Matlab) and from the highest xcorr values I have extracted multiple signals instance from the main data set.
It occurs some times the list include slightly different signals and I wanted to keep/remove those signal by again comparing with the reference signal by finding whether this matches or not. Any efficient way to do that ?
Reference snapshot attached.

we must know the type of the modulation signal, ASK or FSK type used in this case, for general signal x and y is comparison of amplitude and the time (ms), on the 250 ms the signal down -1.7 or -1.8, signal a and b is not matched so the result analysis must be different not same
