Abstract
Un controlador de la capa del medio de control de acceso (MAC) puede manejar datos de la capa base y datos de la capa mejorada en un sistema de modulacion en capas. El controlador de la capa MAC puede procesar tanto los datos de la capa base como los datos de la capa mejorada y mapear los símbolos codificados en una constelacion de modulacion en capas cuando ambos están presentes. Si se terminan los datos de una delas capas, entonces el controlador de la capa MAC puede generar y suministrar datos de relleno predeterminados a la capa que carece de datos adicionales. El controlador de la capa MAC puede enviar una senal de control al hardware de capa física para hacer que el hardware mapee las senales en capas que tienen los dados de relleno en una constelacion de senal modificada. El controlador de MAC puede además generar un mensaje de encabezamiento que indica la que están los datos de relleno. El receptor puede recibir el mensaje de encabezamiento y puede usar la informacion para configurar el receptor para la constelacion de modulacion en capas o la constelacion de senal modificadaAn access control media (MAC) layer controller can handle base layer data and enhanced layer data in a layer modulation system. The MAC layer controller can process both the base layer data and the enhanced layer data and map the encoded symbols in a layered modulation constellation when both are present. If the data in one of the layers is terminated, then the MAC layer controller can generate and supply default padding data to the layer that lacks additional data. The MAC layer controller can send a control signal to the physical layer hardware to make the hardware map the signals into layers that have the fill dice in a modified signal constellation. The MAC controller can also generate a header message indicating what the filler data is. The receiver can receive the header message and can use the information to configure the receiver for the layered modulation constellation or the modified signal constellation
