Full-Duplex Wireless using USRP N210


In this tutorial we'll use node11-10 in the main grid (equipped with a USRP N210) to transmit and receive a single frequency over the air to demonstrate full-duplex wireless capability using the Columbia FlexICoN's Gen-1 Frequency-Flat Amplitude- and Phase-based RF Canceller. For more information, please read

"T. Chen, J. Zhou, N. Grimwood, R. Fogel, J. Marasevic, H. Krishnaswamy, and G. Zussman, “Demo: Full-duplex Wireless based on a Small-Form-Factor Analog Self-Interference Canceller,” in Proc. ACM MobiHoc?’16, 2016. PDF"

We also thank Mahmood Baraani Dasterjerdi for his contributions.

Hardware / Software Resources utilized

  1. USRP N210 with node11-10 in the ORBIT main grid
  2. SUB-20: The SUB-20 is a multi interface USB adapter for providing popular interfaces between PC (USB host) and different hardware devices. Specifically, we use the SPI module on SUB-20 to control and configure our hardware. The user manual can be found here.
