Description

Full-duplex (FD) wireless communication, the simultaneous transmission and reception of wireless signals on the same frequency channel, has garnered significant attention from the research community over the past decade. Software-defined radio (SDR) has become instrumental in bridging the gap from theory to implementation, providing the flexibility necessary to design and deploy FD radio nodes, links, and networks. As part of the Full-Duplex Wireless: From Integrated Circuits to Networks (FlexICoN) project, we have developed three generations of IC-based FD radios that utilize GNU Radio as the primary control and signal processing platform. This paper presents an overview of the design considerations and techniques for implementing FD in GNU Radio, from the transmit and receive signal processing chains to broader testbed integration.
