Shape adaptive three dimensional cone filter bank

Abstract

Three dimensional (3D) shape adaptive cone filter banks are ideally required for selectively filtering of sampled broad band 3D plane wave signals on the basis of their energy distribution. In the proposed design, the shape of each band of the conventional 3D cone filter bank has been adapted based on the energy distribution of the spatio-temporal (ST) 3D plane wave signal. The proposed filter bank is effective for broadband plane wave filtering whose direction of arrival is known a priori. The experimental results prove the robust performance of the proposed shape adaptive 3D cone filter bank in each band of the filter bank.
