Super-exponential algorithms for multichannel blind deconvolution

Multichannel blind deconvolution has received increasing attention during the last decade. Recently, Shalvi andWeinstein proposed an attractive approach to single-channel blind deconvolution called the superexponential methods The objective of this correspondence is to extend the Shalvi andWeinstein approach to the multichannel case and present superexponential algorithms for multichannel blind deconvolution. We propose three approaches to multichannel blind deconvolution. In the first one, we present a multichannel super-exponential algorithm. In the second one, we present a super-exponential deflation algorithm. In the third one, we present a two-stage super-exponential algorithm.
