Super-exponential algorithms for multichannel blind deconvolution

Multichannel blind deconvolution has received increasing attention during t he last decade. Recently, Shalvi and Weinstein proposed an attractive appro ach to single-channel blind deconvolution called the super-exponential meth ods The objective of this correspondence is to extend the Shalvi and Weinst ein approach to the multichannel case and present super-exponential algorit hms for multichannel blind deconvolution. We propose three approaches to mu ltichannel blind deconvolution. In the first one, we present a multichannel super-exponential algorithm. In the second one, we present a super-exponen tial deflation algorithm. In the third one, we present a two-stage super-ex ponential algorithm.
