This paper describes an algorithm that exploits multipath propagation for position estimation of mobile receivers. We apply a novel based on recursive Bayesian filtering, named Channel-SLAM. approach treats components as signals emitted from virtual transmitters, which are time synchronized to the physical transmitter and static in their positions. Contrary other approaches, Channel-SLAM considers also paths occurring due multiple numbers reflections or scattering well combination. Hence,...
Networks of micro aerial vehicles (MAVs) equipped with various sensors are increasingly used for civil applications, such as monitoring, surveillance, and disaster management. In this article, we discuss the communication requirements raised by applications in MAV networks. We propose a novel system representation that can be to specify different application demands. To end, extract key functionalities expected an network. map these into building blocks characterize needs. Based on insights...

Teams of mobile robots will play a crucial role in future missions to explore the surfaces extraterrestrial bodies. Setting up infrastructure and taking scientific samples are expensive tasks when operating distant, challenging, unknown environments. In contrast current single-robot space missions, heterogeneous robotic teams increase efficiency via enhanced autonomy parallelization, improve robustness functional redundancy, as well benefit from complementary capabilities individual robots....
Recovering high-quality 3D human motion in complex scenes from monocular videos is important for many applications, ranging AR/VR to robotics. However, capturing realistic human-scene interactions, while dealing with occlusions and partial views, challenging; current approaches are still far achieving compelling results. We address this problem by proposing LEMO: LEarning MOtion priors 4D body capture. By leveraging the large-scale capture dataset AMASS [38], we introduce a novel smoothness...
Technologies envisaged for a 5G communications system provide interesting prospects which are beneficial co-operative positioning. Since development is in the early stages, there unique opportunity to develop and integrate mobile radio based positioning technology from beginning. In this paper we discuss concepts ensure seamless by cooperative positioning, terminals (MTs) collaborate help each other determine their own position. We address key like smaller cells, higher MT densities...
A multitude of autonomous robotic platforms collectively organized as a swarm attracts increasing attention for remote sensing and exploration tasks. navigation system is essential the to localize itself well external sources.

This knowledge allows move in way not only account mission objectives but also enhance information. Position information classical systems has already been...
Today's mobile radio systems deploy reference signals which can be used or are even dedicated for signal propagation delay-based terminal positioning. Usually, the power of such is uniformly distributed over available spectrum. It known from estimation theory that a uniform distribution not optimal delay estimation. In this paper we consider positioning based on in uplink case. For positioning, introduce parametric waveform. This waveform provides scalar parameter controlling Using aim to...
In this paper, we show that a multi-mode antenna (MMA) is an interesting alternative to conventional phased array for direction-of-arrival (DoA) estimation. By MMA mean single physical radiator with multiple ports, which excite different characteristic modes. contrast arrays, closed-form mathematical model of the response, like steering vector, not straightforward define MMAs. Instead one has rely on calibration measurement or electromagnetic field (EMF) simulation data, discrete. To perform...
Autonomous robotic swarms are envisioned for a variety of sensing applications in space exploration, search and rescue, disaster management. An important capability swarm is spatio-temporal processes such as radio wave propagation seismic activities. The spa-tio-temporal properties these dictate the required position time accuracy, well update rate. A dedicated wireless communication system needs to be jointly designed information exchange, self-localization, sensing. In this article, we...
