“…The communication between any two agents is sent through a wireless radio channel and is mainly dominated by the line-of-sight (LOS) component [18]; thus, the communication link established between them is a Rician fading channel. In the literature, notably in the studies of multi-UAV communications [21], [22], statistical fading models of a UAV-to-UAV link often assume that the signal propagation experiences Rician fading [43].…”

“…On the other hand, research efforts in the communication community have identified that one of the most critical design issues in multiagent systems is interagent communication, which faces many challenges, as these systems have to provide reliable communications between agents to transmit the traffic data of their missions, e.g., sensor, video, and communicationrelaying data, with the multi-UAV system being a typical example [9], [10], [19]. Hence, great efforts have been made to address the design and implementation problems associated with multi-UAV communications [17], [19], [20] and analyze the performance of multi-UAV communications from the perspective of the ergodic capacity, outage performance, and diversity-multiplexing tradeoff [21], [22].…”

The focus of this study is a joint analysis of the stability of formation control and the capacity of wireless communications between agents moving in a formation. The main results derived in this study show a connection between the second moment stability/convergence of formation control and the expected capacity of the data communications for multiagent systems in which the collective behavior of the multiple agents is dominated by formation control with random errors. More specifically, by developing a joint control-communication framework for the performance analysis, we investigate whether random errors in the formation control have a destructive influence on the data communications between agents. We prove that the expected capacity of the multiagent data communication link has a nonvanishing lower bound that can be evaluated through second moment performance analysis. The results from simulations indicate that the theoretical analysis provides reasonable lower bounds for different system parameters.

“…1 Although one could argue that spectrum scarcity can be addressed via an FD-UCS, i.e., UAVs and GSs operating in FD mode, such a system may encounter challenges in meeting FD transceiver design requirements due to size, weight, and power restrictions imposed upon UAVs. As such, the HBD paradigm enables existing HD-UCS to be retained while improving spectrum utilization, with applications seen in aeronautical communication systems [8], [14], UCSs [7], [15], [16], and cellular systems [17], [18].…”

“…Although UAV communications in the presence of shadowing has been studied in the literature, e.g., [2], [41], [42], these works have not considered Rician shadowed fading or Rician fading and are only valid for interference-free scenarios. For interference management strategies, the II approach has already been investigated from the outage probability perspective for aeronautical communications over Rician fading channels [8], [14], and for UAV communications over Rician fading channels [16] and Rician shadowed fading channels [15]. In particular, the work in [15] presented new power series expressions for statistics associated with the Rician shadowed fading model.…”

A hybrid-duplex (HBD) UAV communication system (UCS), i.e., HBD-UCS, to improve spectrum utilization is investigated in this work. By considering the combined effect of fading and shadowing, a comprehensive outage probability analysis of the HBD-UCS under various inter-UAV interference and shadowing scenarios over Rician shadowed fading channels is conducted. It is demonstrated that the ground station (GS) in full-duplex (FD) mode operates at lower outage probability than in half-duplex (HD) mode. Furthermore, the joint detector is shown to achieve lower outage probability than the interference ignorant (II) detector and HD-UCS, even when severe shadowing is encountered. As such, utilizing joint detectors in an HBD-UCS enables multi-UAV networks to achieve high reliability when operating in urban environments.

MOTIVATION AND RELATED LITERATURE Although utilitarian, multi-UAV networks are mired with its own set of challenges that must be addressed. Of particular importance is the lack of available spectrum for UAV communications [5], [6]. Despite the allocation of parts of The associate editor coordinating the review of this manuscript and approving it for publication was Jiayi Zhang. the L-band and C-band for UAV control and non-payload communications (CNPC) by the International Telecommunications Union (ITU) [5], spectrum scarcity is still a challenge. In particular, many other existing systems, e.g., aeronautical communication systems, are also operating on both the L-band and C-band [5]-[7]. In this aspect, a hybrid-duplex (HBD) UAV communication system (UCS), i.e., HBD-UCS, can be a direct solution address spectrum scarcity in UAV communications. The HBD paradigm enables UAVs with existing half-duplex (HD) communication systems, i.e., HD-UCS to simultaneously operate on the same spectrum with full-duplex (FD) ground stations (GSs), effectively doubling spectrum efficiency. However, the simultaneous transmission and reception of signals results in self-interference (SI) at the FD-enabled GS, which can be mitigated via passive or active SI mitigation architectures [8], [9]. The former entails introducing path loss and shadowing, e.g., through antenna placements, while the latter involves canceling SI in the analog or digital domain [9]. Even after SI mitigation, residual SI can still remain due to non-ideal FD transceiver impairments, such as carrier phase noise and imperfect
