v42 v43 3 3 4 4 === Description === 5 In this tutorial, we'll use node11-10 in the main grid (equipped with a USRP N210) to transmit and receive a single frequencyover the air to demonstrate full-duplex wireless capability using the Columbia [http://flexicon.ee.columbia.edu/ FlexICoN]'s Gen-1 Frequency-Flat Amplitude- and Phase-based RF Canceller. Pictures of the FlexICoN RF canceller and node11-10 in the main grid equipped with full-duplex capability are below:5 In this tutorial, we'll use node11-10 in the main grid (equipped with a USRP N210) to transmit and receive a single tone over the air to demonstrate full-duplex wireless capability using the Columbia [http://flexicon.ee.columbia.edu/ FlexICoN]'s Gen-1 Frequency-Flat Amplitude- and Phase-based RF Canceller. Pictures of the FlexICoN RF canceller and node11-10 in the main grid equipped with full-duplex capability are below: 6 6 ||||||Figure 1: The ORBIT-FlexICoN Full-Duplex Node|| 7 7 || [[Image(FlexICoN-gen1-canceller.jpg, 325px)]] [[Image(FlexICoN-gen1-canceller-label.png, 350px)]] || [[Image(FlexICoN-gen1-node11-10.jpg, 400px)]] || 8 8 || (a) The FlexICoN RF Canceller Box || (b) Full-Duplex SDR at node11-10 in the ORBIT grid || 9 9 10 ==== Paper====10 ==== Technical Report ==== 11 11 For more information, please read: 12 12 13 13 ''Tingjun Chen, Mahmood Baraani Dastjerdi, Jin Zhou, Harish Krishnaswamy, and Gil Zussman, “Open-access full-duplex wireless in the ORBIT testbed,” arXiv preprint: 1801.03069 [cs.NI], Jan. 2018.''
