v60 v61 45 45 You 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. 46 46 47 ==== A Real-Time Full-Duplex Radio with OFDM PHY ====47 ==== A Real-Time Full-Duplex Radio with OFDM PHY (GNU Radio + UHD) ==== 48 48 * 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. 49 49 … … 53 53 * 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). 54 54 55 || [[Image(flexicon_orbit_grc_ofdm_node_tab0.png, height= 400px)]] || [[Image(flexicon_orbit_grc_ofdm_node_tab1.png, height=400px)]] || [[Image(flexicon_orbit_grc_ofdm_node_tab2.png, height=400px)]] ||55 || [[Image(flexicon_orbit_grc_ofdm_node_tab0.png, height=333px)]] || [[Image(flexicon_orbit_grc_ofdm_node_tab1.png, height=333px)]] || [[Image(flexicon_orbit_grc_ofdm_node_tab2.png, height=333px)]] || 56 56 ||||||Time-domain Rx signal after RF and digital SIC (@tab0), frequency-domain Rx signal after RF and digital SIC (@tab1), and estimated digital SI canceller coefficients on the packet-level (@tab2). || 57 57 58 ==== In Terminal 1 (UHD) ====58 ==== A Simple Full-Duplex Radio Experiment (Terminal + UHD) ==== 59 59 * Prepare the Eigen library (you can skip this step since the image already contains the Eigen library): 60 60 {{{
