| Résumé : | The in-band full-duplex (IBFD) wirelesscommunication can achieve not only appreciable throughputgain but also is a key technology to enable concurrent radar andcommunication by one hardware. In such a system, an analogself-interference (SI) canceller is essential so that the receivedsignal can be processed digitally to achieve sufficient SNRfor IBFD communication. Unlike the previous similar workswhich rely on a classical matched filter, this paper derives therange-Doppler profile from the state of an adaptive filter, whichprimarily is applied to cancel the residual SI. Using standardIEEE 802.11ac signal, the proposed waveform-independenttechnique in this paper is simulated in a multi-target IBFDscenario. Furthermore, we employed a proof of concept setup tovalidate the proposed approach. The simulation and experimentalresults confirm that our method can render accurate rangeand velocity detection, and potentially satisfies a wide spectrumof opportunistic wireless sensing applications, ranging fromhand/body gesture detection to tracking and localization. |
