The student will participate in the Columbia FlexICoN project (joint with Columbia EE CoSMIC Lab) focusing on the design and implementation of full-duplex wireless communication testbed composed of National Instruments (NI) Universal Software Radio Peripheral (USRP) Software-Defined Radios (SDRs). The project will explore architectures and algorithms that can allow radios to achieve simultaneous transmission and reception on the same frequency channel. The project involves designing/implementing signal processing blocks and self-interference-cancellation/MAC layer algorithms on USRPs. The student will also be involved in integrating the custom-design full-duplex radios into the city-scale COSMOS testbed for evaluating the system in real-world environments.
