I also need to change the modulation schemes for different channel environments. Actually, I am working on adaptive modulation schemes in my experiments. However, I don't find an option to change the modulation schemes in UHD. (I saw those options in python based non-uhd codes, e.g. benchmar_Rx and benchmark_Tx). Are there any programs like that in UHD codes that allow change of modulation schemes?Gnuradio implements many modulation schemes. UHD provides an interface to send/recv baseband samples. You should use gnuradio w/ UHD to implement a receiver and transmitter chain. I highly recommend installing gr-uhd component and getting familiar w/ gnuradio-companion: http://code.ettus.com/redmine/ettus/projects/uhd/wiki#Gnuradio-UHD -Josh
Also, a good book on digital signal processing might be helpful.
