Feasibility of Full-Duplex Radio
Abstract
We have built a testbed for full-duplex radio with which we can control and process time-domain waveforms in real time. We have developed new methods for radio self-interference cancellation that are robust to transmission noise and hardware imperfections. These methods include new architectures of all-analog radio self-interference cancellation and online tuning methods. We have investigated the performance limits of all-analog radio interference cancellation subject to random interference channel instead of just some fixed scenarios. We have developed a method to handle IQ imbalances effectively. We have analyzed the performance of a radio capable of both full-duplex and half-duplex, and obtained a trade-off relationship between full-duplex and half-duplex in the presence of residual self-interference. This project has enabled us to identify the key problems in radio self-interference cancellation and consequently to develop a new and better approach which we will continue to investigate.
