[Discuss-gnuradio] QAM Mod and QAM Demod block in GRC

Hi all,

 

I’m working on an experiment which needs to modify qam modulation block in gnuradio. But I cannot find the source C++ file the qam blocks use. e.g., OFDM demod block uses digital_ofdm_frame_sink in gnuradiobuild/gnuradio/gr-digital/lib. What about qam blocks?

Thank you for your help!

 

Best,
