Millimeter Wave Band Wireless Channel Measurement Techniques in Automotive Applications
Vychodil, Josef ; Kovář, Pavel (oponent) ; Masopust, Jiří (oponent) ; Derbek, Vojtěch (vedoucí práce)
This doctoral thesis deals with the millimeter wave band wireless channel measurement techniques in automotive applications. After a brief introduction into the topic and the summary of the current channel measurement techniques, the goals --- the development and assembly of a measurement system, capable of capturing all of the millimeter wave band channel features and practical measurements with this system, are set. The next part is the core of the dissertation --- the developed channel sounder is presented and a detailed description of used methods, principles, hardware and data processing is given. A significant part of the thesis is dedicated to the mitigation of the unwanted effects caused by the non-linear components in the measurement chain. The last chapters show the results of practical measurements of various scenarios --- the intra-car channels, vehicle to vehicle channels as well as vehicle to infrastructure channels.
