1 lip 2024 · Ultra Wide Band (UWB) technology has enabled the development of precise time synchronization protocols. The intrinsic properties of this technology allow an accurate estimation of the time of flight (ToF) of the radio signal in scenarios covering short distances.
12 gru 2018 · Direct Sequence Ultra-Wideband (DS-UWB) and Time Hopping Ultra-Wideband (TH-UWB) are two variants of the IR technique. These IR techniques DS-UWB and TH-UWB are different multiple access techniques that spread signals over a very wide bandwidth.
9 gru 2020 · The performance of printed wideband antennas has to be optimized both in frequency and time domains, to qualify for UWB applications. This is especially true in multi-resonant antenna topologies where the excitation of different modes can change phase centers and radiation patterns with frequency.
This book presents the theory, analysis, and design of ultra-wideband (UWB) radar and sensor systems (in short, UWB systems) and their components. UWB systems find numerous applications in the military, security, civilian, commercial and medicine fields.
This paper presents a brief overview of two UWB techniques, covering Impulse-Radio UWB (IR-UWB) and Frequency-Modulation UWB (FM-UWB) methods. The link margin enhancement technique, Very-WideBand (VWB), and power consumption reducing technique, chirp UWB, are also introduced.
The parameter that has been estimated by various research groups for UWB channel modeling is the channel impulse response (CIR), a direct figure of merit for time domain analysis that is the indelible feature of any ultrawideband system [8, 13].
UWB is an IEEE 802.15.4a/z standard technology optimized for secure micro-location-based applications. It enables distance and location to be calculated indoors or outdoors with unprecedented accuracy – within a few centimeters – by measuring the time it takes radio signals to travel between devices. Along with centimeter-level
