“…However, increased sophistication in attackers' devices demands for improved radio-frequency (RF) security technologies [1]. Cooperative jamming and randomized waveforms can be used to enhance security [2][3][4]. These systems' performance can be further enhanced by RF convergence, since waveforms used for jamming can be employed for communication, remote sensing (e.g., radar), and spectrum monitoring to support the security-oriented operations.…”

This paper introduces and justifies a novel system concept that consists of full-duplex transceivers and uses a multifunction signal for simultaneous two-way communication, jamming and sensing tasks. The proposed device structure and waveform enable simple-yet-effective interference suppression at the cost of being limited to constant-envelope transmissionthis is a weakness only for the communication functionality that becomes limited to frequency-shift keying (FSK) while frequency-modulated continuous wave (FMCW) waveforms are effective for jamming and sensing purposes. We show how the transmission and reception as well as different interference and distortion compensation procedures are implemented in such multifunction transceivers. The system could be also applied for simultaneous spectrum monitoring with the above functions. Finally, we showcase the expected performance of such a system through numerical results.
