Abstract

Un dispositivo de comunicacion inalambrico recibe los datos de audio desde una estacion base via un enlace de comunicacion de una frecuencia de radio (RF) (es decir, un enlace hacia adelante) y transmite los datos de audio a la estacion base via el enlace de comunicacion RF (es decir, un enlace inverso). El dispositivo de comunicacion inalambrico usa la funcionalidad inherente del enlace inverso, que incluye un dispositivo (120) de entrada de audio para determinar si el dispositivo de comunicacion inalambrico se opera en un medio ambiente de ruido alto. Un analizador (124) de senales analiza la senal de audio en el enlace inverso y determina si el nivel de ruido ambiental excede el umbral predeterminado. Si es asi, el analizador (124) de senales activa un filtro (126) para filtrar la senal de audio proporcionada a un transductor (122) de salida de audio. La banda limitante de la senal de audio provista al transductor (122) de salida de audio, mejora la inteligibilidad de la senal de audio en la presencia de ruido.
