摘要
In-band full-duplex (IBFD) technology has the potential to not only double the communication throughput but also enable additional capabilities.The fusion of radar and communication subsystems is an excellent example of how IBFD facilitates integration of radar functionality into a communication system.Developing and analysis of a joint IBFD radar-communication (RadCom) system is at the core of this study.This system derives the range-Doppler image from the state of an adaptive filter, which already exists in a typical IBFD transceiver.Our approach is waveform-independent and reuses the RF front-end while it requires little additional digital logic.The proposed system is prototyped to assess the modemradar coexistence in a real-world IBFD communication link budget.Employing the prototyped system, we quantify the additional required logic resources and investigate whether such a RadCom approach dictates a trade-off between the two intended functionalities.The experimental results show that the proposed solution enables a communication system to detect targets within 20 m while maintaining an IBFD link with another communication node.
