    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) ====
     47=== Example Experiment 1: 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.

    113115 In this example, since the TX power level is at 0dBm, a total amount of around 90dB self-interference cancellation is achieved, of which 45dB is obtained by the Gen-1 RF canceller, and 50dB is obtained by the digital cancellation.
