Abstract

U 5. generaciji (5G) bežičnih komunikacijskih sustava, očekuje se ispunjavanje zahtjeva
koji nadmašuju mogućnosti prethodnih tehnologija. U tom kontekstu, neortogonalni višestruki
pristup (NOMA) izdvaja se kao obećavajuća tehnika za rješavanje tih izazova. NOMA
omogućuje podršku većem broju korisnika nego što je broj ortogonalnih resursnih slotova,
koristeći neortogonalnu raspodjelu resursa. Ova sposobnost poboljšava efikasnost korištenja
spektralnih resursa i povećava kapacitet... More mreže, čime se omogućuje veći broj istovremenih
korisnika. U usporedbi s konvencionalnim ortogonalnim pristupima (OMA), NOMA pokazuje
značajne prednosti u skalabilnosti i učinkovitosti, što je ključno za zadovoljenje globalnih
potreba za brzinom i kvalitetom komunikacije u 5G mrežama. Rad analizira i uspoređuje
tehnike višestrukog pristupa specifične za različite generacije mobilnih mreža, s naglaskom na
njihove prednosti i izazove. Razumijevanje ovih tehnika i njihova pravilna primjena ključni su
za optimizaciju performansi i učinkovitosti mreža, a NOMA će igrati ključnu ulogu u daljnjem
razvoju i poboljšanju 5G mreža. Less

Abstract (english)

In the 5th generation (5G) wireless communication systems, it is expected that requirements
will exceed the capabilities of previous technologies. In this context, Non-Orthogonal Multiple
Access (NOMA) stands out as a promising technique to address these challenges. NOMA
enables support for a larger number of users than there are orthogonal resource slots by using
non-orthogonal resource allocation. This capability enhances spectral efficiency and increases
network capacity,... More allowing for a higher number of simultaneous users. Compared to
conventional Orthogonal Multiple Access (OMA) methods, NOMA shows significant
advantages in scalability and efficiency, which are crucial for meeting global demands for speed
and quality of communication in 5G networks. The paper analyzes and compares multiple
access techniques specific to different generations of mobile networks, focusing on their
advantages and challenges. Understanding these techniques and their proper implementation is
crucial for optimizing network performance and efficiency, and NOMA will play a key role in
the continued development and enhancement of 5G networks. Less
