Need power line communication modelling in Simulink

I'm studying about the best how to sent data over an AC line. First I want to know how channel characteristics are.

So, Anyone could tell me how powerline channel like. Previously I've red some papers which related to this field are here.

It would be great if you also give me some example of simulink files or how to implement it in simulink.
