Abstract

Se describe un método y aparato para evaluar la interferencia dentro de un intervalo de tiempo de una senal TDMA. Se calcula una potencia de senal recibidapromedio respecto de multiples segmentos de repeticion contenidos dentro de un intervalo de tie mpo TDMA. Los tamanos de segmento dependen de la eficiencia delesquema de codificacion con correccion de errores que utiliza el tipo de canal seleccionado. Las potencias de senal recibidas calculadas para los multiplessegmentos se aplican a un filtro de paso bajo. La salida del filtro de paso bajo se procesa con el objeto de determinar el nivel de interferencia dentro delintervalo de tiempo.
