Abstract: Hyperspectral cameras capture electromagnetic information within hundreds of narrow spectral bands, producing hyperspectral images (HSIs) with the capability to accurately characterize the attribute information of objects. However, mixed noise induced by instrument and atmospheric effects… read more here.

Abstract: Abstract A method for estimating signal and noise subspaces in the context of direction of arrival (DOA) for coherent wideband orthogonal frequency-division multiplexing (OFDM) signals is proposed. It relies on a newly defined matrix, which… read more here.
