statistical characteristics study of human Blockage Effect in future indoor millimeter and sub millimeter wave wireless communications
Vehicular Technology Conference, 2018Co-Authors: Bile Peng, Sebastian Rey, Dennis M Rose, Soeren Hahn, Thomas KuernerAbstract:The millimeter and sub-millimeter wave communication is a promising solution to future indoor multi-gigabit wireless communications because of its huge available bandwidth. One of the key difficulties is the hu- man Blockage Effect since the human body can no longer be considered as being "transparent" as at lower frequencies. In this paper a study of statistical characteristics of this problem is presented. At first, broadband measurements of human Blockage are provided. Afterwards, a realis- tic mobility model for indoor movements of humans is adopted and elliptic cylinders are applied to approximate human bodies in ray-launching simulations. Consequently, the distributions of Line-Of-Sight (LOS) path and Blockage durations as well as Blockage numbers are obtained by simulations. Finally, the system performance in presence of the distributed antennas is evaluated.

procedure for determining the wind tunnel Blockage correction factor
International Conference “New Technologies Development and Applications”, 2020Co-Authors: Ernad Beslagic, Samir Lemes, Fuad HadžikadunicAbstract:Before launching a new wind turbine, it is necessary to determine its output performance. The performance can be achieved either by testing the complete wind energy converter in actual operating conditions in the natural environment or by testing the wind turbine in a wind tunnel. In addition to the many advantages offered by wind tunnel testing, there are also some disadvantages. One of them is the appearance of a Blockage Effect that occurs when wind turbines are tested in a closed test section of a wind tunnel.
