Abstract

Se proporciona un método para una alerta de alta penetración en un sistema vía satélite. Se genera un mensaje para la transmisión a una terminal inalámbrica. El mensaje se divide en varios símbolos, cada símbolo está compuesto de una porción del mensaje. Los símbolos son codificados vía la codificación FEC para generar los símbolos codificados externos, y cada símbolo codificado externo se codifica basándose en una secuencia ortogonal binaria correspondiente. Los símbolos codificados internos son modulados basándose en un esquema de modulación binario, y tienen forma de pulso para generar ráfagas del mensaje para la transmisión a la terminal inalámbrica. Cada ráfaga del mensaje refleja un grupo de los símbolos codificados internos, en donde la agrupación de los símbolos codificados internos facilita la detección de la secuencia conjunta por la terminal inalámbrica, y cada ráfaga del mensaje exhibe una relación de pico a energía promedio relativamente baja.
