FlexICoN: A Self-Interference-Cancelling Full-Duplex Radio Enabling Next-Generation Wireless Communications [D33]

Full-duplex (FD) wireless is an emergent wireless communication paradigm that can greatly improve wireless network performance but is also fraught with fundamental challenges. FD operation involves simultaneous transmission and reception at the same frequency, resulting in the tremendous transmitter self-interference at the receiver input. This self-interference can be a billion times more powerful than the desired signal to be received. In this demo, an FD radio that consists of a software-defined radio, an analog self-interference cancellation circuitry, and a circulator with an antenna will be presented. We will demonstrate simultaneous transmission and reception at the same frequency channel with self-interference suppression across the antenna, analog, and digital domains to achieve cancellation with nearly one part-per-billion accuracy. This demo is part of the FlexICoN (http://flexicon.ee.columbia.edu/) project at Columbia University.
