Beamforming in the Reproducing Kernel Domain Based on Spatial Differentiation
Takahiro Iwami, Naohisa Inoue, Akira Omoto
This paper proposes a novel beamforming framework in the reproducing kernel domain, derived from a unified interpretation of directional response as spatial differentiation of the…
