Abstract

Ovaj rad daje uvod u tehnologiju i principe pametnih antenskih sustava, s posebnim naglaskom na procjenu smjera dolaska signala. Proučavani su MUSIC i ESPRIT algoritmi, uz pretpostavku da na antenski niz dolaze koherentni signali. Kako bi se procijenili smjerovi dolaska koherentnih signala, primjenjena je tehnika prostornog izglađivanja prema naprijed/konjugirano unatrag. MUSIC i ESPRIT algoritmi uz prednje/konjugirano stražnje prostorno izglađivanje proučavani su i uspoređivani pomoću simulatora izrađenog za tu svrhu. Kao moguća primjena procjena smjerova dolaska signala na antenski niz, dan je pregled RF sustava za pozicioniranje.

Abstract (english)

This thesis gives an introduction to smart antennas technology and principles with special attention given to DOA (Direction of Arrival) estimation. MUSIC and ESPRIT algorithms were studied, with assumption of coherent arriving signals. To resolve DOA estimation problem under coherent signals condition, forward/conjugate backward spatial smoothing technique was employed. MUSIC and ESPRIT with forward/conjugate backward spatial smoothing were studied and compared using a simulator created for that purpose. An overview of RF positioning systems is given as a possible application of DOA estimations.
