N2 - A microphone array increases the speech intelligibility in challenging acoustic situations. By creating a highly directive pick-up pattern, influences such as room reflections (i.e. diffuse noise) and other spatial noise sources can be minimized. In the course of this work, various planar microphone arrangements are discussed and subsequently combined with different types of fixed beamforming techniques. A special focus has been taken on spiral and spiral-like topologies that are compared to each other for Delay-and-Sum (DS), Minimum-VarianceDistortionless-Response (MVDR) and a particular case of Filter-and-Sum (FS) beamforming, i.e. the WeightedLeast-Squares (WLS) optimization. Fundamentals of Microphone Arrays A general system model according to Fig. 1 can be used to derive the basic equations for a microphone array being composed of an arbitrary microphone topology and a choice of fixed beamforming weights. Considering a Collapse
