The Usage of Absorption Material for Multi-Path Mitigation Methods Using a Compact Reconfigurable Channel Emulator
Abstract
The study of mitigation methods for signal transmission in wireless environments featuring multi-path conditions is a growing subject of great interest. The Compact Reconfigurable Channel Emulator (CRCE), currently under development, is a table-top instrument utilized to emulate these, among other, conditions and provides ease and reliability in testing absorption material as a mitigation method. Used in anechoic chambers, this material is capable of reducing noise in signal transmission and, in differing quantities, recreating fading. To permit this, the CRCE will have a robotic arm for variable material exposure and better chamber emulations with precise stirrer blade control. The CRCE's programming has also been modified for such hardware changes with a C++ interface, which combines the power of Labview instrument control and data processing with C++ adaptability. This interface increases user-friendliness, control flexibility, and combines Labview graph-creation of signal transmissions to produce probability density and cumulative distribution functions, which juxtapose transmission power against frequency, time delay, phase delay, or stirrer blade position. This and other software modifcations, and tutorials, not only increase chamber usability but also aid in chamber use for other multi-path experiments. Ultimately, all of these modifications will allow for absorption material efficiency analysis in multi-path environment noise reduction.
