Query regarding combining OFDM and spectrum sense

GNU Radio

hello all,
I am performing an experiment wherein I am combining OFDM receive code
and spectrum sense code as hier_blocks. I am stuck while defining the
usrp_source here. As you all know, the OFDM receive code uses
usrp_source(). The spectrum sense code also uses usrp_source(). I am
not getting how to bring them together? Please help me on this.

Regards,
Shesh

You’ll have to do a bit of refactoring to move the usrp higher in the
hierarchy. FWIW, ofdm/receive_path.py has no reference to the usrp.
