title = "Subspace superdirective beamforming with uniform circular microphone arrays",
abstract = "Superdirective beamformers with uniform circular arrays (UCAs) are often used in communication applications for their steering flexibility and potential high directivity factors (DFs). This paper proposes two classes of subspace superdirective beamformers. The first class is based on the diagonalization of the noise pseudo-coherence matrix with the Fourier matrix while the second one is based on the joint diagonalization of the pseudo-coherence matrices of the desired and noise signals. By properly choosing the dimension of the subspace, the developed two classes of subspace superdirective beamformers can find good compromises between large DFs and reasonable values of white noise gains, which make them much more flexible than the conventional regularized superdirective beamformer.",
