ADS and CST Co-simulation [help]

Hi there,
I am looking for examples of CST/ADS co-simulation of a receiver system. E.g. antenna, amplifier and then some test equipments. My aim is to find out using the co-simulation feature the sensitivity of the system. (i.e. I simulate my antenna in CST MWS and then the amplifer portion in ADS and then include some noise floor limits) Does anyone has an experience of working out such simulation?
Any help will be very much appreciated.

I also want help for the co-simulation of ADS and CST. Can i design a front end in ads and use the antenna of cst and join them together for co-simultaion?
