Stable 2nd Order Adaptive IIR Filter Structure for Blind Deconvolution
In this paper, blind system deconvolution using infinite impulse response (IIR) adaptive filters is studied. A new structure of input-balanced realizations is derived for 2nd order filter. It is showed that the adaptive IIR filter realized with such a structure is bounded-input bounded-output (BIBO) stable and suits for blind equalization based on Bussgang Criterion. Computer simulations are given and discussed to support our theoretical results. A series of the results show that the obtained filter structure is highly recommended for blind deconvolution due to its nice convergence and stability properties during adaptation.
