Self-interference Cancelation Performance in Full-Duplex Jamming and Spectrum Monitoring

The use of drones in illegal activities has increased in recent years. One method for countering their operation in restricted areas is by transmitting a high-powered jamming signal over the frequencies used by the target drone. To improve the performance of jammers, full-duplex is introduced. In full-duplex systems, the transceiver is able to transmit and receive using the same time-frequency resources, which allows a device to conduct spectrum monitoring while preventing drone operations by transmitting jamming. In this study, the self-interference cancelation of typical jamming waveforms is experimentally measured and signal detection is performed over samples with imperfect self-interference cancelation.
