Generování a analýza signálů v bezdrátových přenosových systémech

Abstract

This diploma paper is about the attributes of the wireless communication. It compares various wireless technologies for data transfer. It explains the principles of digital modulation and its influence on the final form of the signal. It discusses the theory of the signal transfer by the transmission environment. It reports about the possibilities of the generating and signal analysis of the various transmission technologies, its advantages and usage in the today’s world. It informs about the modern measuring devices and explains the important signal errors, which fundamentally influence its quality. The principal part addresses the practical proposal of the functional transmission system, which is realized on the modular hardware system platform, where the system function is made up in the flexible development environment. The functionality of the system is verified by the signal generator and analyser at the end of the paper.
