Download Citation | Simulations of Diversity Techniques for Urban UAV Data Links | In urbanized terrain, radiowave propagation is subjected to fading on large-scales and small-scales that would. Simulation and experiment are carried out for channel loss model of UAV in specific areas. The comparison between the measured data and the simulation data shows that this model is effective in UAV link loss calculation, which can provide important theoretical reference for UAV data link communication system by: 1. The three-processing-channel optimum strategy can improve the reliability of UAV data link in complex environments, and this paper presents some technical basis for applications of airborne military data link. 0 2 4 6 8 10 12 10 -6 10 -5 10 -4 10 -3 10 -2 10 -1 10 0 Path loss/dB B E R Performance of high bit rate transmission in flat fading.
The data link is an important part of the UAV, and with ground control station, it can complete the remote control of UAV. Meanwhile, the data link can transmit the airborne information such as. Abstract: In order to test the anti-interference ability of an Unmanned Aerial Vehicle (UAV) data link in a complex electromagnetic environment, a method for simulating the dynamic electromagnetic interference of an indoor wireless environment is proposed. This method can estimate the relational degree between the actual face of an UAV data link in an interface environment and the simulation. Cache-enabled unmanned aerial vehicles (UAVs) have been envisioned as a promising technology for many applications in future urban wireless communication. However, to utilize UAVs properly is challenging due to limited endurance and storage capacity as well as the continuous roam of the mobile users. To meet the diversity of urban communication services, it is essential to exploit UAVs On applying this algorithm to a complex unknown simulation environment constructed based on the parameters of the real UAV, the training experiment results showed that the novel DRL algorithm resulted in a performance improvement exceeding 20% as compared with the state-of-the-art DDPG.
In many situations, the trajectory of an unmanned aerial vehicle (UAV) is very likely to deviate from the initial path generated by a path planning algorithm. This is in fact due to the existence of dynamic constraints of the UAV. In order to reduce the degree of such a deviation, this research introduces a trajectory planning algorithm, the objective of which is to minimize distance while. simulation model, the character and moment law of aircraft . Multi-agent technology is often adopted in system with complex aerodynamic characters, e.g., the formation of the aircraft flight. We can apply the multi-agent as reference in the designing work of the UAV flight simulation system, as UAV . UAV Systems. With the ever increasing requirement for UAV Datalink (Unmanned Aerial Vehicle) applications both in Military Surveillance and Police Surveillance operations, Enterprise Control Systems Ltd are at the forefront of the design and manufacture of microwave surveillance equipment to carry video, data and telemetry signals suitable for integration into UAV platforms. 1. Introduction. In recent years, there is great progress in wireless big data and Internet of Things (IoT), and the requirement on the wireless data rate has been explosively increasing, leading to many new wireless techniques,.Due to the broadcast nature, wireless transmission in the network may be overheard by eavesdroppers, and hence it is of vital importance to guarantee the.
