20.500.12556/DKUM-85135 Ozkopasovni programsko definiran radio s standardnim komunikacijskim vmesnikom magistrsko delo Narrowband software defined radio with standard communication interface Delo prikazuje izdelavo ozkopasovnega programsko definiranega radia. Predstavljen je koncept naprave ter prednosti in slabosti ozkopasovnega programsko definiranega radia v primerjavi s širokopasovnim. Podan je teoretični in tehnoloških pregled. Potek razvoja je prikazan od začetnih zahtev sistema do končnih testov pravilnosti delovanja. Predstavitev je osredotočena na vgrajeno strojno, vgrajeno programsko in programsko opremo. V končnem delu so predstavljeni rezultati, meritve in testi, pridobljeni z izdelano napravo. Osrednja meritev tega dela prikazuje zmanjševanje šuma pri nižji pasovni širini sprejemnika. S tem delo potrdi osrednje izhodišče po izdelavi ozkopasovnega programsko definiranega radia. The work represents the development of a narrowband software-defined radio. The concept of the device and the advantages and disadvantages of a narrowband software-defined radio compared to a wideband one are introduced. A theoretical and technological overview is provided. The development process is shown from the initial system requirements to the final tests of functionality. The presentation focuses on embedded hardware, firmware, and software equipment. In the final section, results, measurements, and tests obtained with the developed device are presented. The central measurement of this work demonstrates noise reduction at a lower receiver bandwidth, thereby confirming the central premise of constructing a narrowband software-defined radio. radio komunikacija program ozkopasovni šum radio communication program narrowband noise true true false [U.
