Parallel Channel Sounder for MIMO Channel Measurements

IEEE Wireless Communications, 2018
In order to address the challenges in MIMO channel measurement and modeling for 5G communication scenarios, a CDM-based parallel channel sounder is developed and evaluated in this article. Compared to traditional TDM-based channel sounders, our parallel channel sounder supports eight-by-eight (8 x 8) MIMO communications, 200 MHz RF bandwidth, 5 ns ...

On co-channel interference measurements

Proceedings of 8th International Symposium on Personal, Indoor and Mobile Radio Communications - PIMRC '97, 2002
The spectral efficiency of a cellular mobile radio system is enhanced through the reuse of the available spectrum. The resulting co-channel interference, however, also limits the system capacity. Power control is needed so that co-channel interference can be maintained within a tolerable bound.

Nonintrusive measurements of the telephone channel

IEEE Transactions on Communications, 1999
Algorithms for a system which performs in-service nonintrusive measurements of telephone line parameters such as echo path delay, echo attenuation, speech and noise levels are presented. It forms the theoretical background of a hardware implementation of the ITU-T P.561 recommendations for nonintrusive assessment of quality of a telephone network for ...

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 ...

Metrology Model of Measuring Channel in Multi-Channel Data-Measurement System

2020 International Conference on Engineering Management of Communication and Technology (EMCTECH), 2020
Developing metrology solutions is of major importance when building data-measurement systems. One of the key issues is evaluating the characteristics of measuring channels built on the basis of digital sensors of physical values. These sensors include a primary analog transducer and an analog-digital converter.

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 ...
