One of the main trends in the area of communication systems is to constantly increase the transmission rates. This trend leads to the need for an ever increasing bandwidth, which will in the future provide primarily the millimeter-wave band in the range of 30-300 GHz. The project is aimed at research into specific propagation characteristics of the millimeter waves in various rugged urban environments and suburban areas. The characteristics of signal multipath propagation in both the space and the time domain will be examined within the project. The project outcome will include statistical and deterministic channel models of stationary and time-varying environments created for different scenarios such as LOS and NLOS propagation, various relative speed and position of transmitter and receiver. Channel models will be created using real measured data. As research in this area is in its beginnings and a number of analyses, primarily for time-varying channels, have not yet been performed, it is expected that the project will bring new and rewarding results.

Description in Czech
Jedním z hlavních trendů v oblasti komunikačních systémů je neustálé zvyšování přenosových rychlostí. Tento trend vede k potřebě stále větší šířky pásma, kterou v budoucnu poskytne především oblast milimetrových vln v pásmu 30-300 GHz. Cílem projektu je výzkum velmi specifických vlastnosti šíření milimetrových vln v různě členitých prostředích městské zástavby i předměstských oblastí. V rámci projektu budou zkoumány vlastnosti mnohacestného šíření signálu a to jak v prostorové tak i v časové doméně. Výstupem projektu budou statistické i deterministické modely kanálů pro stacionární i časově proměnná prostředí vytvořené pro různé scénáře jako je přímá a nepřímá viditelnost, různá vzájemná rychlost nebo poloha vysílače a přijímače. Modely kanálů budou vytvořeny na základě reálných dat získaných měřením. Protože výzkum v této oblasti je na svém počátku a řada analýz především v oblasti časově proměnných kanálů nebyla dosud provedena, lze očekávat, že projekt přinese nové a přínosné výsledky.
