Abstract

Sistemas y métodos para la predistorsión digital de radiofrecuencia en un transmisor multibanda. El transmisor multibanda incluye un sistema de conversión ascendente digital configurado para convertir digitalmente de modo ascendente señales de entrada digitales a fin de proveer señales de radiofrecuencia digitales. Cada señal de entrada digital y por lo tanto cada señal de radiofrecuencia digital corresponde a una banda diferente de una señal de transmisión multibanda a ser transmitida por el transmisor multibanda. El transmisor multibanda también incluye un sistema de predistorsión digital de radiofrecuencia configurado para predistorsionar digitalmente las señales de radiofrecuencia digitales a fin de proveer las señales de radiofrecuencia digitales predistorsionadas y un combinador configurado para combinar las señales de radiofrecuencia digitales predistorsionadas a fin de proveer una señal de radiofrecuencia digital predistorsionada en multibanda.
