“…The reason for choosing the gamma function as a benchmark for the comparison is that the value of Γ(4) can be calculated easily and that this integral appears in (7) when the function α(r) is a polynomial. The error of the numerical calculation must be 10 −10 or less because the total cancellation performance of 100 dB or more is necessary for IBFD systems.…”

Although in-band full-duplex (IBFD) communication can theoretically double the spectral efficiency compared with conventional wireless communication technologies, it cannot be realized without reducing a high-power self-interference (SI) signal. Since the SI signal is affected by nonlinear distortion of radio-frequency (RF) circuits of its own terminal, cancellation systems capable of removing the nonlinear distorted SI have been actively developed. Detailed theoretical analysis based on the authors' past literature shows that for IBFD using a nonlinear self-interference canceller, the symbol error rate is improved when the power amplifier has certain distortion characteristics rather than being ideally linearized. However, it is not yet known what amplifier characteristics are best for the IBFD system. In this study, we theoretically analyze the self-interference signal to clarify the optimum amplifier characteristics for the IBFD system. An optimization problem to obtain an optimum transfer function from theoretical analysis is formulated as an Rayleigh quotient with constraints, and we introduce a numerical technique to solve the optimization problem. By numerical experiments, we show that the SI cancellation performance, signal-tointerference-distortion-plus-noise ratio (SIDNR), and amplifier's power efficiency are improved by the optimization.

“…In light of these developments, electronic warfare technology has become a vital factor in ensuring electromagnetic space security [7], while the potential threat to wireless communication security has attracted widespread public attention [8][9][10]. The continuous progression of wireless communication technology has resulted in an increasingly crowded electromagnetic spectrum [11,12]. The interference generated by the 5G frequency band of mobile phones on the C-band of satellite communication serves as a salient example.…”

The relay function of unmanned aerial vehicles (UAVs) is playing an increasingly important role in wireless communication systems, as UAVs often perform tasks at high altitudes and can avoid the impact of ground obstructions on the communication links between ground communication devices, thereby enhancing the reliability and communication capacity of the links. Meanwhile, UAVs have more degrees of freedom and can achieve optimal position deployment and robust anti-jamming performance through flexible adjustment of spatial position. However, the premise for UAVs to achieve the above advantages is accurate modeling and analysis of the wireless communication channel, as well as the deployment of reasonable joint geographic-electromagnetic domain optimization (JGEDO) algorithms to fully utilize their own degrees of freedom. Due to the increasing threat posed by the current electronic warfare environment to the normal communication of UAVs, this article focuses on environments with malicious jamming and geographic obstacles, and constructs a communication system composed of a base station (BS), a relay UAV, and several remote ground robots (RGRs). On the basis of considering multipath fading and estimation error of jammer position, the expected value of instantaneous average signal-to-interference-ratio (SIR) for the entire system is derived. Taking this indicator as the optimization objective, this article develops a joint optimization algorithm for the position of the UAV and the mainlobe width of UAV antenna beams. Numerical simulation verifies the effectiveness of this algorithm compared to traditional algorithms.

“…Advances in the self-interference (SI) cancellation research are facilitating FD operation [1] that potentially allows to simultaneously combine wireless communications and electronic warfare functions. This entails, e.g., simultaneous signals reception and jamming, to prevent eavesdropping and increase the security of wireless systems, or simultaneous surveillance and jamming, to increase the efficiency of electronic counter-measure systems [2]. As such, FD radio technology is a promising candidate for improving the reliability and also security of wireless systems.…”

In this article, we study the advantages and disadvantages that full-duplex (FD) radio technology brings to remotecontrolled drone and counter-drone systems in comparison to classical half-duplex (HD) radio technology. We consider especially the physical-layer reliability perspective that has not yet been comprehensively studied. For establishing a solid analytical background, we first derive original closed-form expressions to evaluate demodulation and detection performance of frequencyhopped and frequency-shift keyed drone remote control signals under external or self-inflicted interference. The developed analytical tools are verified by comparison to simulated results and then used to study the impact that the operation mode has on the operable area of drones and effectiveness of counterdrone systems in different scenarios, linking the physical layer performance to practical safety. Analysis of the scenarios shows that FD operation compared to HD can improve the effectiveness of a counter-drone system and that in FD mode a drone can detect the attacks from the counter-drone system from a greater distance than in HD mode. However, two-way communication between the remote controller and drone in FD mode compared to HD significantly reduces the drone's operable area when targeted by a smart counter-drone system.
