Abstract  Abstract

FIELD: radio engineering digital encoding of broadband signal. SUBSTANCE: method and device which ensure efficient modeling of harmonic structure of speech spectrum use several types of low-pass filters as applied to code vector of fundamental tone. Tone giving highest amplifying factor of prediction that is least error of prediction of fundamental tone is chosen and corresponding parameters of code dictionary of fundamental tone are selected. EFFECT: enhanced quality of reconstructed signal. 63 cl 4 dwg
