Advanced MIMO techniques for fifth generation radio mobile networks

U ovom diplomskom radu opisan je razvoj antenskih rješenja za radijske mobilne mreže počevši od jednoantenskih do naprednih višeantenskih MIMO sustava. Objašnjen je način rada MIMO sustava i sve pojedine tehnike koje se u njemu koriste i predstavljen je njegov napredak prema masivnom MIMO sustavu koji je ključan za razvoj 5G mreže i pouzdanijeg i boljeg Interneta stvari. Uz zahtjeve koje masivni MIMO sustav mora omogućiti za 5G mreže i Internet stvari dat je i uvid u sve nedostatke i ograničenja naprednih višeantenskih sustava.This thesis describes the development of antenna solutions for mobile radio networks starting from single-antenna to advanced multi-antenna MIMO systems. The mode of operation of the MIMO system and all individual techniques used in it are explained as well as its progress towards the massive MIMO system, which is crucial for the development of the 5G network and more reliable and better Internet of Things. In addition to the requirements that a massive MIMO system must provide for 5G networks and Internet of Things, there is also an insight into all the shortcoming and limitations of advanced multi-antenna systems
