Abstract

Mejoras a un implementación de modulación recubierta (MR) están expuestas. El proceso actual expone dos implementaciones de MR, usando transpondedores simples y múltiples por frecuencia de senal, respectivamente. El MCF8 jerárquico recubierto (J-MCF8) es un caso especial de ML. Re-codificando la porción de alta prioridad (AP) de una senal J-MCF8, la MR puede mejorar la razón ruido-para-transportador (RTR) de una senal J-MCF8. La MR puede ser simulada por computadora y una senal de dos cubiertas puede ser secuencialmente desmodulada con una capacidad RTR pronosticada. Una senal MR puede ser simulada usando senales vivas para procesamiento fuera de línea. En adición, un aparato de procesamiento de la senal puede procesar senales MR de tiempo real emuladas de senales satélite vivas.
