Abstract
Hlavným cieľom tejto práce bolo vyvinúť demonštračnú platformu pre implementáciu algoritmov na odhad smeru príchodu signálu. Celkovo bolo opísaných šesť techník, ktoré boli následne implementované v Pythone spolu so simuláciami príchodu signálov. Bola vykonaná štúdia dostupného hardvéru, v ktorej boli porovnané rozdiely medzi na mieru prispôsobenými a voľne dostupnými riešeniami. Navrhli sa konkrétne hardvérové a softvérové konfigurácie pre praktickú implementáciu metód odhadu príchodu signálu. Na záver boli navrhnuté experimentálne merania na overenie účinnosti implementovaných metód. Vykonali sa testovacie merania a ich výsledky boli kriticky zhodnotené.
The main objective of this thesis was to develop a demonstrator platform implementing signal processing algorithms for signal direction of arrival estimation. In total, six estimation techniques were described, and simulations of discussed beamforming and subspace-based methods were implemented in Python. A study was conducted on available hardware, comparing trade-offs between customised and off-the-shelf solutions. Specific hardware and software configurations were proposed for practical implementation of the estimation methods. Finally, a testbed was constructed to verify the performance of the implemented estimation methods. Tests were performed, and the results were critically evaluated.
