Identification of acoustic path transfer function component in beamforming structure

Abstract

This paper presents identification technique of minimum phase component from acoustic transfer function between two inputs and sound source, where two acoustic path transfer functions are analyzed as unknown system in beamforming structure.

Spatial based beamforming for acoustic communications

“…This broadband characteristic suggests the adoption of narrow band methods on smaller frequency segments, and such operations are replicated across the entire bandwidth. Various beamforming algorithms, such as eigenvector-based [2][3], direction-of-arrival (DOA) based [4], and channel transfer function based methods [5], require accurate estimation of the spatial correlation matrices.…”
