Title:
A Method for Wideband Direction-of-Arrival Estimation Using Frequency-Domain Frequency-Invariant Beamformers 
Abstract:
In this paper, we propose a new wideband direction-of-arrival (DOA) estimation method for wideband smart antennas based on Frequency-Domain Frequency-Invariant Beamformers (FDFIB). By appropriately designing the weights for frequency-domain beamformers at different frequencies, the frequency-invariant beam-patterns are obtained. Then beamformers play a role as (wideband) spatial processor transforming signals from element-space to beam-space. After that, the narrowband DOA methods can be applied...    »
