Abstract

"DISPOSITIVO PARA SUPRESSãO DE ECO". Processos e aparelhos são apresentados para modelar de forma paramétrica ruído de fundo e gerar ruído de conforto em sistemas para supressão de eco. De acordo com concretizações típicas, um modelo de ruído de fundo é baseado sobre um conjunto de parâmetros modelo de ruído que são por sua vez baseados sobre medições de ruído de fundo efetivo em um sistema de supressão de eco. As concretizações típicas incluem modelos auto-regressivo, de média móvel auto-regressivo e de domínio de freq³ência. Um modelo de média móvel auto-regressivo e de domínio de freq³ência de primeira ordem típico inclui um único zero fixo e um único pólo variável. O zero único e o pólo único são suficientes para proporcionar inclinação espectral apropriada no ruído modelado resultante, e o único zero assegura que o modelo seja incondicionalmente estável. A integração dos modelos de ruído paramétrico típico com vários dispositivos de supressão de eco é também exposta.
