Chaotic tangles in subsystems of radiofrequency channel

Duration: 01.01.2015 — 31.12.2017

On the project

Within this project we will focus on enhancement and deeper understanding of phenomena related with non-linear radio-frequency subsystems. One of the main assets of this project is a development of new models that will serve for accurate modeling of communication components. Thus we will obtain unique and valuable knowledge that will lead to more reliable, accurate and faster simulation methods. The participant team is composed to form forefront in exploring this topic and will focus theoretically as well as experimentally on resolving set goals. The research team believes that the proposed project is sui generis with promising outcomes.

Description in Czech
Zaměření projektu spočívá v rozšíření a prohloubení vědomostí o jevech souvisejících s nelineárními radiofrekvenčními systémy. Jedním z hlavních přínosů projektu je vytvoření nových modelů, které budou aplikovány na přesné modelování komponentů komunikačního řetězce. Tímto způsobem získané znalosti povedou k vytvoření spolehlivějších, přesnějších a rychlejších simulačních metod. Řešitelský tým je složen tak, aby měl výrazný vědecký potenciál ve zkoumání uvažovaných témat a na řešení vytyčených cílů se zaměří po teoretické i praktické stránce. Vědecký tým věří, že zaměření projektu lze považovat za tematicky originální s perspektivními výsledky.
