Microphone arrays for beamforming
Grénar, Milan ; Smékal, Zdeněk (referee) ; Míča, Ivan (advisor)
The aim of the bachelor's thesis is to assemble theoretical and practical information about methods for estimate direction of arrival whereas there is an emphasis on beamforming. There are introduced general conventions which are being used to measure with multichannel microphone array. Part of this thesis is the implementation of the DAS beamformer in several modifications, including verification of the functionality in ideal and real conditions.

Statical acoustical sources localization
Mikeš, Petr ; Holešinský, Pavel (referee) ; Míča, Ivan (advisor)
The microphone array can be used in many important applications. The primary usage, which most of other applications are based on, is only: acoustic sources localization and separation of each signal from their compound. The microphone array is usually included in ordinary mobile phones, where it reduces noise and sound of its surrounding that otherwise degrades vocal speech. Other microphone array utilization is in for example speech identification, speakers’ localization or signal isolation of one speaker.

Design of portable microphone array
Vazovan, Ľubomír ; Kubík, Michal (referee) ; Klapka, Milan (advisor)
The subject of this thesis is the structural design of portable five-arms microphone array to localize noise sources, which is using to beamforming techniques. The aim of the work is to design a simple and easy mechanical construction. Part of the work is the solution to connect the measurement microphone to the construction field. The first part is devoted to the theory of beamforming, design the microphone array for beamforming and offered an overview of plane mic fields. The next part of my work is drafting the proposals selected nodes from which you select a specific design. In conclusion I evaluate the economics of construction.
