Abstract

U ovom radu su navedeni i objašnjeni osnovni diskretni modulacijski postupci obrade signala, tehnike višestrukog pristupa, MIMO sustavi. Navedena je i podjela frekvencijskog spektra u Republici Hrvatskoj za sustave mobilnih mreža četvrte generacije. Digitalni modulacijski postupci omogućuju prilagodbu informacije za prijenos digitalnim komunikacijskim sustavima. Informacije se prenose preko radiofrekvencijskog spektra koji je ograničen stoga ga je bitno racionalno iskorištavati pomoću tehnika višestrukog pristupa koje omogućuju pristup komunikacijskom sustavu većem broju korisnika istovremeno. Cilj ovoga završnog rada je objasniti tehnologije potrebne za prijenos signala mobilnim komunikacijskim sustavom te pridonijeti boljem razumijevanju tih tehnologija.

Abstract (english)

In this final thesis basic discrete modulations, signal processing, multiple access techniques, and MIMO systems are discussed and explained. The distribution of the frequency spectrum in the Republic of Croatia for the fourth generation mobile networks is also shown. Digital modulation procedures enable adaptation of information for transmission of digital communication systems. Information is transmitted over a limited radio frequency spectrum, so it is essential to exploit it rationally through multiple access techniques which allow larger number of users to access a communication system simultaneously. The purpose of this final thesis is to explain the technologies needed to transmit signals in the mobile communication system and to contribute to a better understanding of these technologies.
