AN OPTIMIZATION TECHNIQUE FOR ITERATIVE FREQUENCY-DOMAIN DECONVOLUTION

This paper, presents a new technique for the optimization of the iteration (design) parameter of filters used in frequency-domain iterative deconvolution methods. The proposed technique implies the filter optimization be performed in the frequency-domain instead of the time domain, which translates into tremendous saving of computation time. In addition, the technique provides a quantitative measure of the performance of the filter regarding noise reduction and filtration error. This paper includes illustrative examples using both computer simulation as well as experimental data. The demonstrations show that the technique yields reliable results for the deconvolution of signals in the presence of noise. © 1990 IEEE
