During the *Signal Generator Back-to-Basics Webcast*, hosted by Agilent Technologies, on 29 February 2012, we received a number of real-time questions from a broad audience. 

If one person asks - someone else will want to know the answer too - so we have captured various questions and answers and are posting them individually here, in this Forum, for your future reference and immediate enjoyment!

*Question: I would like to know about the OFDM modulation. How can interference effects be prevented, as in this case the signals are at the same frequency, at the same time, but with different modulation. Some effects such as desensitization or cross modulation could still impair the receiver's front-end? How is it solved?*
