A class of new criteria for blind deconvolution

摘要

Complex signal and system models are considered in this paper, a class of new eriteria, which is based on higher-order cumutant is derived for blind deconvolution, it is pointed out that blind deconvolution may be realized by maximize or minimize the normalized cumulant of the system output, this exhibit a new approach of statistics matching for blind deconvolution. As an example, a new blind deconvolution (equalization) algorithm is proposed, and computer simulation results are included to demonstrate the performance of the proposed algorithm.
