The robust algorithms for optimization of nonrecursive filter coefficients by the combined criterion of minimum mean-square error

S. N. Kirillov, S. M. Shubin


The authors report of development and tests of new robust algorithms for optimization of nonrecursive digital filters based on a combined criterion of minimum of the mean-square error. The latter contains information concerning variation of the synthesis inaccuracy. The algorithms suggested are shown to provide a decrease by 1.7 dB in the dynamic range of the error signal at the output of the filter under synthesis, and exhibit low sensitivity to inaccurately set initial parameters.
