Abstract

<B> MéTODO E APARELHO PARA DETECTAR E CARACTERIZAR SINAIS EM UM SISTEMA DE COMUNICAçãO <D>. Um aparelho e método para detectar e caracterizar sinais em um sistema de comunicação fornece detecção eficiente de voz, tom e ruído, o que reduz o volume de recursos de processamento consumidos e também distribui a demanda de processamento durante um período. A presente invenção fornece tal detecção eficiente de voz, tom e ruído aplicando a Função de Diferença de Magnitude Média (AMDF) durante intervalos de tempo distintos para avaliar variações em altura de som durante um período, permitindo que uma hipótese seja formulada quanto a se um sinal é sinal de voz, de tom ou de ruído. Duas métricas novas são computadas que caracterizam o sinal quanto à altura de som e à variação em altura de som. é aplicada lógica baseada em regra para detectar transições entre os tipos de sinais.
