Direction of arrival estimation using wavelet based beam-space MUSIC
Ismail I. Jouny, M.G. Amin · 2002
Angle of arrival estimation using beam-space MUSIC is implemented by nonuniformly subbanding the spatial spectrum of an antenna array using the wavelet transform. The resulting spatial spectrum is thus composed of beam-space elements with dyadically proportional beamwidths. Wavelet based spatial filtering is compared with that of the DFT in the context of direction of arrival estimation (DOA) performance.
