Abstract

En la supresión de interferencia de intermodulación se recibe una señal de prueba digital (x) y se obtiene una potencia de la señal de prueba digital recibida (243). Sobre la base de la potencia obtenida, se obtiene al menos un valor modelo a partir de un modelo (244) que modela los valores modelo de una no linealidad en amplitud y fase de una señal recibida que pasa a través de componentes pasivos y componentes activos en el receptor. Los valores modelo corresponden a una pluralidad de potencias de la señal recibida. Entonces, se suprime la interferencia de intermodulación multiplicando (245) la señal de prueba digital recibida con el al menos un valor modelo obtenido, para de ese modo obtener una señal de prueba digital de salida (x) de la cual se suprime la interferencia de intermodulación causada por el receptor.
