Abstract

Se describe un dispositivo de linealización (380), que está configurado para determinar los parámetros de distorsión previa asociados con una pluralidad de amplificadores no lineales (331, 332, 333, 334), cada uno asociado con una característica de amplificador no lineal. El dispositivo de linealización comprende un circuito de determinación (383), un primer puerto (381) y un segundo puerto (382). El primer puerto está configurado para recibir una pluralidad de coeficientes de canal indicativos de las características de canal de una pluralidad de trayectorias de comunicación (391, 392, 393, 394) entre la pluralidad de amplificadores no lineales y un receptor de observación de transmisión (370). El segundo puerto está configurado para recibir, desde el receptor de observación de transmisión, una suma de señales de transmisión generadas por la pluralidad de amplificadores no lineales y transferidas a través de la pluralidad de trayectorias de comunicación. El circuito de determinación está configurado para determinar los parámetros de distorsión previa con base en la pluralidad recibida de coeficientes de canal, la suma recibida de señales de transmisión y un modelo de las características de amplificador no lineal de los amplificadores no lineales. También se dan a conocer una disposición, nodo de transmisor inalámbrico, nodo de servidor basado en la nube, método y producto de programa de computadora correspondientes.
