Abstract
A novel spatio-temporal (ST) three dimensional (3D) adaptive filter bank has been proposed based on the optimization techniques. The proposed adaptive algorithm is defined to track the 3D broadband spatio-temporal plane wave signal. For designing such an adaptive 3D filter bank, the orientation of 3D broadband plane wave signal in frequency domain has been tracked and aligned to the direction of axis of the filter bank. The initial results demonstrates the potential of the proposed 3D adaptive filter bank to first seek, track and pass\attenuate (depending upon the IIR filter design) wide-sense stationary 3D broadband plane wave signals based on their direction of arrival.
