Calibration of the measurement channels of measurement systems following graduation of the channels

Measurement Techniques, 2013
Questions related to determining the parameters of the transfer function of the measurement channels of measuring systems, insertion of corrections, and subsequent estimation of the metrological characteristics of the channels are considered.

Simultaneous channel measurements of the on-body and body-to-body channels

2016 IEEE 27th Annual International Symposium on Personal, Indoor, and Mobile Radio Communications (PIMRC), 2016
In this paper, we characterize the simultaneous channel response of narrowband on-body and body-to-body channels at 2.48 GHz using the κ-μ fading model. The measurements considered three nodes, two of these were located on the front-chest and front-central-waist of an adult male, and the third node was located on the front-central-waist of an adult ...

Channel polarization and Blackwell measures

2016 IEEE International Symposium on Information Theory (ISIT), 2016
The Blackwell measure of a binary-input channel (BIC) is the distribution of the posterior probability of 0 under the uniform input distribution. This paper gives an explicit characterization of the evolution of the Blackwell measure of an arbitrary symmetric BIC under Arikan's polarization transform, and uses this characterization to provide a ...

Measurements and Consistent Families of Quantum Channels

Open Systems & Information Dynamics, 2011
This article introduces the notion of consistent families (Λ(n))n≥1of quantum channels. These families correspond to simultaneous observation of different copies of a given quantum system. Here, we are primarily interested in the analysis of measurements connected with them.

Channel Measurements and Channel Traces

2016
Channel properties and characteristics of real cellular mobile networks are investigated in this chapter. The conducted measurements serve the purpose of a) highlighting the properties of cellular networks in order to design a novel congestion control protocol and b) collecting channel traces to emulate real network behavior in a simulated environment.

Channeling measurements methodology

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 1993
Abstract A complete set of methods for channeling measurements is presented. It is based on a full discussion of transformations between laboratory and crystal frames of reference. Specific methods include crystal orientation and goniometer calibration procedure, beam-goniometer misalignment analysis, beam alignment along an arbitrary ...

Drug-ionic channel interactions: Single-channel measurements

Annals of Neurology, 1984
Ionic channels of excitable membranes are the basic site where ionic fluxes take place during the generation of action potentials. A variety of natural toxins, chemicals, and therapeutic drugs have been found to modify the gating kinetics of the Na+ channels, thereby altering the excitation pattern.
