Abstract

<B> APARELHO E MéTODO PARA DETEMINAçãO DE TAXA EM UM SISTEMA DE COMUNICAçãO <D> Para determinar precisamente taxa e atividade de voz em razões de sinal para ruído de moderada a baixa (SNRs), para maximizar parâmetros de qualidade de voz, capacidade de sistema e/ou vida de bateria, parâmetros de um sistema para supressão de ruído são utilizados para entradas para a função de determinação de taxa. Utilizando este método, um volume maior da fala é extraído do ruído de fundo e um número mais baixos de inícios falsos durante condições de ruído em flutuação em comparação com sistemas convencionais, é detectado. O método é vantajoso para detecção de atividade de voz (VAD) bem como determinação de taxa (RDA) e ao contrário de outras implementações RDA/VAD, é independente do tipo de codificador de fala empregado (IS-127, CDG-27, IS-96 E GSM).
