An innovative Volumetric Current Meter (VCM) was designed in order to allow quick velocity measurements in open channels. At first, the coefficient of velocity (Cv) of the device was determined through calibration under different water velocities in the laboratory. The measurement performance was verified by measurements performed in similar flows in irrigation channels using an ordinary curren...

We study the power of measurements implementable with local quantum operations and classical communication (or LOCC measurements for short) in the setting of quantum channel discrimination. More precisely, we consider discrimination procedures that attempt to identify an unknown channel, chosen uniformly from two known alternatives, that take the following form: (i) the input to the unknown cha...

The Neutrino Factory has been proposed as a facility to provide an intense source of neutrinos suitable for the measurement of neutrino oscillation parameters and a possible CP violating phase to unprecedented precision. In the Neutrino Factory, neutrinos are produced by the decay of a muon beam with 20-50 GeV per muon. Initially, the muon beam occupies a large volume in phase space, which must...

Prior to recent advances in computational electromagnetics, a deterministic timedomain simulation of a wireless channel was deemed too expensive to implement. Conventionally, wireless channel designers use more practical measurement-based techniques, involving statistical models or channel transfer functions [1–3]. However, despite their convenience, such techniques can be inaccurate and lead t...

We propose a metrological strategy reaching Heisenberg-scaling precision in the estimation of functions any fixed number $p$ arbitrary parameters encoded generic $M$-channel linear network. This scheme is experimentally feasible since it only employs single-mode squeezed vacuum and homodyne detection on single output channel. Two auxiliary networks are required their role twofold: to refocus si...

Comprehensive knowledge of the channel and accurate channel models are essential in the optimized system design. In the Wireless Body Area Network (WBAN) applications, use of Ultra Wideband (UWB) transmission as well as close presence of human body, bring their own major challenges in the channel modeling. Several channel models have been proposed and numerous channel measurement campaigns have...

Problem statement: Multiple Input Multiple Output (MIMO) wireless communication system is an innovative solution to improve the bandwidth efficiency by exploiting multipath-richness of the propagation environment. The degree of multipath-richness of the channel will determine the capacity gain attainable by MIMO deployment. Approach: Therefore, it is very important to have accurate knowledge of...

Realistic spatial channel models are essential for development of future wideband mobile communication systems, particularly when adaptive antennas at the base stations are considered. Channel models are prerequisite for the performance evaluation of different adaptive antenna solutions and estimation of the obtained capacity gain. Realistic models require channel measurements to prove their as...

This paper reviews the double directional channel models mainly for MIMO applications. First, the double directional channel measurements and data analysis are presented, to extract the antenna-independent propagation channel model from the MIMO channel measurement via the parametric modeling and estimation. Next, stochastic modeling approaches are introduced for the link-level simulation for t...

We have performed extensive radio channel measurements in different radio environments at 2.15 GHz frequency. A spherical array and a wideband radio channel sounder were utilized at the mobile station in order to characterize the spatial radio channel at the mobile. The measurement setup, presented in [1], enables the full 3D spatial and polarization characterization of the wideband mobile radi...
