I have to simulate two microwave QAM signals(2 and 2.5 GHz), and the task says the minimum Adj. channel interference is 40 dB. How can I take this into account in my simulation, preferring simple solutions?

You can refer to the model which demonstrates simulation of Adjacent and Co-Channel Interference on a PSK modulated signal.
To open the Simulink model, run the following command in MATLAB command line:
openExample('comm/AdjacentAndCochannelInterferenceExample')
You can simulate the interference on a QAM modulated signal on the similar lines.

Thanks a lot. Do you have any idea to set the midband frequency(carrier) of the modulated signal, and the length of the channel?
