Abstract: |
Third-order central moments have been shown to be well suited as objective functions for blind deconvolution of impulsive signals. On-line implementations of such algorithms may suffer from increasing filter norm, forcing adaptation under constrained filter norm. This paper extends a previously known efficient algorithm with self-stabilizing properties to the case of using a third-order moment objective function. New results herein use averaging analysis to determine adaptation stepsize conditions for asymptotic stability of filter norm. |
