s-parameter mathematical theory for crosstalk analysis

[yefj]

Hello, I have a system shown in the photo .I have S-parameters of this system there are several tests like
1.integrated crosstalk noise which uses victim S-params near end and far end cross talk
2.PSXT (power sum cross talk)
3.MDNEXT(multi distributed NEXT)
4.Normalized MDNEXT.
Is there some theory or even better a code which takes VNA s-param data and shows how its been calculated exactly based on the S-params?

I did a Google search on deriving NEXT from s-parameters and got some good hits (videos and articles). Maybe try that same search to see if you find some useful resources...

Hello , I did google too before posting they dont show exact matematical manual to derive it.
Is there some recoomended manual I could use?

The technical reference mentioned in the AI overview seems to address NEXT pretty well:
