Abstract

The Restricted Structure(RS)optimal deconvolution filtering problem for Multi-Channel (linear and nonlinear) discrete-time systems is considered in this paper. The main contribution of the paper lies in developing the numerical procedure for designing reduced order estimators in multivariable cases. Two simulation examples are used to illustrate the results. These are: the enhancement of the lung and the heart sound signals and the automotive air-fuel ratio estimation problem.
