    4545You will need to login into the full-duplex node (by {{{ssh root@node11-10}}}) in two separate terminal windows lo for running the experiment: one for the main full-duplex transceiver UHD program and one for controlling the RF canceller.

     47==== A Real-Time Full-Duplex Radio with OFDM PHY (GNU Radio + UHD) ====
    4848* Within the FD node (i.e., {{{ssh -X root@node11-10}}}, open the GNU Radio flowgraph {{{~/flexicon_orbit/fd_transceiver_ofdm/grc/ofdm_node_fd.grc}}} in {{{gnuradio-companion}}}, as shown below.

    5353* Run the experiments, three plots will show up: Time-domain Rx signal after RF SIC and digital SIC (@tab0), frequency-domain Rx signal after RF SIC and digital SIC (@tab1), and the estimated coefficients of the digital SI canceller taps (@tab2).
