Abstract  Abstract

communications engineering. SUBSTANCE: noise suppression system implemented in communication system functions among other things to generate updating by monitoring deviation of spectral energy and to ensure forced updating basing on predetermined threshold criterion. Spectral energy deviation is determined by means of element using exponentially weighted components of spectral power. Exponential weighting is a function of input-signal present energy; the higher the input-signal energy the longer is exponential aperture and vice versa the lower the signal energy the shorter is exponential aperture. System also prevents forced updating during intervals of continuous transient input signals such as musical ones. EFFECT: improved decision taken on updating noise estimate in case of sudden increase in background noise level. 30 cl 10 dwg
