Abstract :
A novel spatio-temporal (ST) three dimensional (3D) cone-stop filter bank is proposed having a highly selective cone-shaped stop band in 3D frequency space. The direction of the axis of the cone and the band width of the cone may be independently controlled and adapted over space-time. Preliminary results are given for the 2D (fan-stop) case that demonstrate the potential of the proposed filter bank to adaptively seek, track and attenuate wide-sense stationary broad band plane waves (PWs) having directions of arrival (DOAs) in the fan-shaped stop band while transmitting similar PWs having DOAs in the pass band.
