Abstract

Métodos y aparato para el reordenamiento dinámico de paquetes. En un aspecto, se proporciona un método para procesar los datos del intervalo improvisadamente para producir paquetes descifrables, en donde los datos del intervalo incluyen símbolos de modulacion intercalados. El método incluye desintercalar un flujo de los símbolos de modulacion intercalados para producir un flujo de los símbolos de modulacion, calcular flujos paralelos de las métricas LLR en base al flujo de los símbolos de modulacion, y mapear los flujos paralelos de las métricas LLR para producir un flujo de paquetes descifrables. En otro aspecto, se provee un aparato que incluye logica de desintercalacion para desintercalar un flujo de los símbolos de modulacion intercalados para producir un flujo de los símbolos de modulacion, logica de procesamiento métrica configurada para producir flujos paralelos de las métricas LLR en base al flujo de los símbolos de modulacion, y logica de mapeo configurada para mapear los flujos paralelos de las métricas LLR para producir un flujo de paquetes descifrables.
