This paper presents a full-duplex wireless transceiver design that enables simultaneous transmission and reception on a single channel with minimal impact on link reliability. The design combines RF and baseband techniques to achieve full-duplexing. Antenna cancellation is introduced as a novel technique for self-interference cancellation, which, when combined with RF and digital interference cancellation, achieves around 60dB of self-interference reduction. This allows a node to simultaneously transmit and receive. The design is implemented using off-the-shelf hardware and software radios, and experiments show that the full-duplex prototype achieves median performance within 8% of an ideal full-duplex system. The paper discusses the potential benefits of full-duplexing, including solving problems such as hidden terminals, congestion, and end-to-end delays in wireless networks. It also explores the limitations of the design, including transmit power, size, and bandwidth. The full-duplex system uses two RF chains per node to achieve nearly twice the throughput of a half-duplex system. The paper also discusses the impact of bandwidth on antenna cancellation and the limitations of existing interference cancellation techniques. The paper evaluates the performance of the full-duplex system in real-world experiments, showing that it achieves 84% median physical layer throughput gain compared to half-duplex operation. The system is shown to be feasible for narrowband systems, but has limitations for signals with bandwidth greater than 100MHz. The paper also discusses the application of full-duplexing in wireless networks, including reducing hidden terminals, congestion, and end-to-end delays. It also explores the use of full-duplexing in cognitive radio systems. The paper concludes that while full-duplexing has limitations, it offers significant benefits for wireless communication.This paper presents a full-duplex wireless transceiver design that enables simultaneous transmission and reception on a single channel with minimal impact on link reliability.
