Hi Ahmed,My tentative answer is 'yes', NI's RF hardware and drivers can to multicarrier generation. For instance, the DeveloperZone has an example for OFDM which is a multicarrier scheme [1]. What kind of signal are you looking to generate, and what are the characteristics of your carriers? Depending your exact needs, the application may become easier or more difficult.[1] LabVIEW Modulation Toolkit OFDM Example<a href="http://zone.ni.com/devzone/cda/epd/p/id/3456" target="_blank">http://zone.ni.com/devzone/cda/epd/p/id/3456</a>
