Adaptive Wideband Beamforming with Combined Spatial/Temporal Subband Decomposition

摘要：

An adaptive wideband beamforming structure with a lower computational complexity and higher convergence speed is proposed, which is achieved by combined spatial/temporal subband decomposition. First, the received array signals are processed by a transformation matrix, and then split into subbands by a series of analysis filter banks. At each subband, an independent beamformer can be operated, where some of the lower subbands can be discarded without affecting its performance due to the highpass filtering effect of the transformation matrix.
