“…e.g., Koivisto and Tuukkanen [20] considered in-band fullduplex (FD) capability as one of the great discoveries in wireless communications. By exploiting simultaneous transmission and reception capability through self-interference cancellation techniques, the FD capability is seen to double the spectral efficiency of wireless data transmission.…”

Cognitive radio (CR) was coined to address evolving user needs two decades ago. Since then, it also has been considered a way to mitigate perceived spectrum scarcity in various application areas. In this article, the status of military CR research is assessed through a systematic literature review of 193 articles, from 2013 to 2020, using IEEE thematic topics, technology readiness levels, as well as comprehensive capability meta-model as analytical frameworks. The annual distribution of military CR research indicates continuing interest. The military CR research seems to be prolific on topics like waveform design and security, not forgetting a steady interest in CR networking topics. Significantly low numbers of papers address applications, services, and standardization. In general, military CR research seemed sporadic and scattered. Our data suggest that a transition from individual techniques, component-level subsystem research in the direction of systems engineering approach, and system-level studies has not yet happened, and the overall TRLs remain low. The absence of publicly articulated comprehensive treatment of the notion of military cognitive radio system is graphic and has led to disjointed, scattered research at the subsystem level.

“…The polarization diversity based isolation approach has limitation of using different polarizations for T x and R x modes. Moreover, the polarization diversity is not desirable in many wireless communication including wireless remote sensing systems and communication systems for military applications [29]. The co-polarized antennas for such applications can achieve isolation through the combination of differential feeding (near field SIC) and single-tap analog/RF domain based SIC circuitry [31].…”

Single Layer, Differentially Driven, LHCP Antenna With Improved Isolation for Full Duplex Wireless Applications

et al. 2019

This paper presents a unidirectional, left handed circularly polarized (LHCP), single layered antenna array with improved interport isolation for simultaneous transmit and receive (STAR) or in-band full duplex (IBFD) wireless applications. The proposed IBFD antenna is comprised of three identical and sequentially rotated LHCP radiating elements where two R x patches are symmetrically placed with respect to a single T x patch. The symmetry of proposed antenna structure results in same amount of coupling or self interference (SI) from T x element and differentially driven R x patches achieve effective suppression of resulting SI to obtain improved T x-R x interport isolation required for STAR applications. The deployed feed network for differential-driven R x operation is composed of a simple 3dB/180 • rat-race coupler (ring hybrid coupler) with nice in-band amplitude and out-of-phase balance characteristics. The implemented single layer, compact (antenna elements and feeding network etched on single-layered PCB) antenna array achieves 10dB return-loss bandwidth ≥ 75MHz for both T x and R x ports. The prototype achieves ≥ 47dB interport isolation in 75MHz bandwidth and 3 dB axial ratio beam-width is ∼ 60 • for implemented antenna. INDEX TERMS Left hand circular polarized (LHCP) antenna, improved interport isolation, in-band full duplex, self interference cancellation (SIC), 3dB/180 • ring hybrid coupler.

“…However, what still remains a largely unknown aspect of the IBFD technology are its potential applications in defense and security [7]. While the improvement in spectral efficiency is important in itself also in tactical networks [8], [9], military full-duplex radios (MFDRs) can give an advantage also by other means through electronic warfare, as we have envisioned at a concept level [10], [11] and recently demonstrated in a laboratory environment under limited transmit power [12]. In this work, we perform a measurement-based evaluation of the specific scenario depicted in Fig.…”

This paper provides experimental results regarding an emerging physical-layer concept within the field of military communications, viz. the full-duplex 'radio shield', by building on the recently discovered full-duplex technology that allows an individual radio device to simultaneously transmit and receive (STAR) on the same spectrum. Its basic idea is to protect the surroundings of a radio device by broadcasting powerful jamming while successfully receiving tactical transmissions on overlapping frequencies. The jamming creates a protective dome of interference around such a military full-duplex radio (MFDR). The experimental results reported herein prove that the radio shield yields a large SINR advantage against interception, even though a fully practical full-duplex radio prototype with residual self-interference is used. Moreover, we show that the prototype radio shield is capable of preventing the control of improvised explosives or rogue drones while simultaneously receiving tactical signals. Therefore, the full-duplex radio shield can give armed forces a significant technical lead over an enemy by preventing it from using the frequency band for offensive purposes.
