I want to write ac signal with lets say f=120kHz with amplitude 20Vpp on Power line which has f=50/60Hz with amplitude of 230/220V. I want to know how to design a circuit for it. It would look like the image posted below. And Also would like to know the calculations! THanks in Advance!

You should tell in which language/syntax you need the description.

Simulation languages like (H)SPICE, SPECTRE, ..., analog description language like Verilog-A or aVHDL, or other mathematical description language like MATLAB, or pure mathematical description? Or anything else?
 

Carrier current transmission. Check out the National LM1893 and be aware of the safety issues dealing with the mains! E

I don't know the Proteus software nor its syntax, sorry.

You need 2 (or 3) ac (sinus) voltage sources in series: The first one with 230*√2 V / 50 or 60Hz , a second one with 20V / 120kHz with start=0 and stop=as_you_like (or an exponentially decaying sinus, cf. the image below). If this ac voltage source doesn't have a repeating feature, you'll need a third one - same as the second one - but with a delay of 10ms (in case of 50Hz line frequency). Then try and repeat a 20ms cycle.

Well if your going to make a circuit and generating 120khz Signal! are you just going to give it in a powerline?? Absolutely no! For that you need to make a circuit and i am asking how to do it! Its basically powerline communication!!
