Abstract
Técnicas para administrar la PAPR (relacion entre la potencia pico y la potencia promedio) para la modulacion de multiples portadores en los sistemas de comunicaciones inalámbricos. Las diferentes terminales en un sistema de acceso multiple pueden requerir diferentes potencias para transmitir. La cantidad de portadores a ser asignados a cada una de las terminales es hecha dependiente de su potencia de transmision requerida. A las terminales que requieran una mayor potencia para transmitir es posible asignarles una cantidad menor de portadores (asociada con una menor PAPR) de manera de permitir que el amplificador de la potencia opere con mayores niveles de potencia. A las terminales que requieran menores potencias de transmision puede ser asignada una cantidad mayor de portadores (asociada con una mayor PAPR) ya que el amplificador de la potencia es operado con menores niveles de potencia. Los portadores específicos a ser asignados a las terminales también pueden ser determinados mediante los niveles de potencia de transmision a efectos de reducir las emisiones fuera de banda. A las terminales que requieran mayores potencias de transmision pueden asignárseles portadores cerca del medio de la banda operativa, y a las terminales que requieran menores potencias de transmision pueden asignárseles portadores cerca de los bordes de la banda.
