Typical indoor environments contain multiple walls and obstacles consisting of different materials. As a result, current narrowband radio frequency (RF) navigation systems cannot satisfy the challenging demands for most applications. The RF ultra wideband (UWB) system is promising technology localisation owing to its high bandwidth that permits mitigation multipath identification problem. This work proposes novel UWB accurate mobile robot (MR) in environments. composed two sub-systems: MR...
A self-localized Ultra-Wide-Band (UWB) system that is suitable to navigate mobile robots in indoor environments introduced. In impulse-based UWB systems, positional accuracy inversely proportional the signal bandwidth. work, a number of anchor nodes are located at fixed positions an environment transmitting synchronized 2 ns pulses with Differential Binary Phase Shift Keying (DBPSK) modulation. An receiver mounted on robot utilizes Time Difference Arrival (TDOA) between pairs for...
This work proposes an improved Real Time Localization System using UWB technology, for people and asset tracking in a closed environment, particularly underground mines. The technology has demonstrated very good performance with localization error margin below 41 centimeters. main objective of this was to develop affordable, easy use, scalable system detect mines that allows fast location rescue case disaster. It can also improve the mine productivity under normal conditions. Different tests...
Nowadays the need for dealing with ultra-high speed Analog to Digital Converter (ADC) is becoming more and common, from Telecommunications Precise Instrumentation, every application increasing analog digital interface data rate. The sampling rate of ADCs demands use advanced acquisition techniques as well latest technology available. utilization dedicated Application Specific Integrated Circuit (ASIC) an expensive solution deal very high throughput ADC its lack flexibility a huge drawback....
Configuring and setting up a remote access laboratory for an advanced online school on fully programmable System-on-Chip (SoC) proved to be outstanding challenge. The school, jointly organized by the International Centre Theoretical Physics (ICTP) Atomic Energy Agency (IAEA), focused SoC its applications nuclear scientific instrumentation was mainly addressed physicists, computer scientists engineers from developing countries. use of e-learning tools, which some them adopted others...

In impulse-based UWB systems, positional accuracy is inversely proportional to the signal bandwidth. this work, a number of anchor nodes are located at fixed positions in an indoor environment transmitting synchronized 2.5ns pulses with Differential Binary Phase Shift Keying (DBPSK) modulation. An receiver mounted on mobile robot utilizes Time Difference Arrival (TDOA) between pairs for localization. Self-localization implies that position estimation algorithms run locally robot. A prototype...
Networks are currently essential for computing: It is therefore to guarantee the quality of network links in order ensure a proper operation computing systems. However, widespread deployment monitoring devices might not be economically feasible. In this paper, we propose use Programmable System-on-Chip FPGAs (PSoCs) enabling comprehensive testing networks. Software-only solutions no longer valid, because timescales current networks call custom-hardware solutions. Thus, show that PSoCs...
