Abstract

Un método de procesamiento de una señal de difusión en un transmisor, el método que comprende: correlacionar datos de Conducto de Capa Física, PLP, en una constelación usando Modulación de Amplitud en Cuadratura, QAM; realizar codificación de Múltiples Entradas Múltiples Salidas, MIMO, sobre una primera señal y una segunda señal de los datos de PLP correlacionados en la constelación; construir una primera trama incluyendo la primera señal codificada MIMO y una segunda trama que incluye la segunda señal codificada MIMO; insertar un primer símbolo de preámbulo, P1, y un primer símbolo de preámbulo adicional, AP1, en un comienzo de la primera trama; e insertar el primer símbolo de preámbulo, P1 y el primer símbolo de preámbulo adicional, AP1, en un comienzo de la segunda trama, en donde el símbolo P1 incluye una primera parte de prefijo, una parte principal, una primera parte de sufijo, en donde la primera parte de prefijo transporta una versión cambiada de frecuencia de una parte de la parte principal mientras que la primera parte de sufijo lleva una versión cambiada de frecuencia de la otra parte de la parte principal, en donde un cambio de frecuencia de fsh se aplica a las partes de primer prefijo y sufijo, en donde el símbolo AP1 incluye una segunda parte de prefijo, una parte principal adicional, una segunda parte de sufijo, en donde la segunda parte de prefijo transporta una versión cambiada de frecuencia de una parte de la parte principal adicional mientras que la segunda parte de sufijo lleva una versión cambiada de frecuencia de la otra parte de la parte principal adicional, en donde un cambio de frecuencia de -fsh se aplica a las partes de segundo prefijo y sufijo, en donde la primera trama y la segunda trama cada una incluye además una señal de piloto de un patrón de piloto específico y datos de señalización previa de Capa 1, previa de L1, en donde al menos uno del símbolo AP1 y los datos de señalización previa de L1 incluye información para identificar el patrón de piloto específico incluido en la trama correspondiente, en donde el símbolo P1 incluye una información de tipo de transmisión y parámetros de transmisión esenciales, en donde los datos de señalización previos de L1 se transportan a través de al menos un segundo símbolo de preámbulo, P2, dentro de cada trama y en donde el símbolo P1 se sitúa justo antes del símbolo AP1 y el al menos un símbolo P2 se sitúa justo después 30 del símbolo AP1.
