Abstract

Sistema, que comprende: una estación de base con dos puertos con múltiples entradas - múltiples salidas (MIMO) por canal de datos individual de una pluralidad de canales de datos individuales; y redes de acoplamiento cruzado (1001, 1002, 1003) configuradas para combinar vectorialmente la potencia procedente de un primer puerto de los dos puertos MIMO a un segundo puerto de los dos puertos MIMO por canal de datos individual respectivamente, donde cada red de acoplamiento cruzado comprende dos puertos de entrada y dos puertos de salida, donde una primera señal de entrada sobre uno de los dos puertos de entrada se divide en primeras señales de dos componentes que presentan una primera diferencia de potencia variable entre las primeras señales de dos componentes, donde una de las primeras señales de dos componentes recibe un primer retardo de fase variable para generar una primera señal de componentes retardada, donde una segunda señal de entrada sobre otro de los dos puertos de entrada se divide en segundas señales de dos componentes que presentan una segunda diferencia de potencia variable entre las segundas señales de dos componentes, donde una de las segundas señales de dos componentes recibe un segundo retardo de fase variable para generar una segunda señal de componentes retardada, donde una señal de componentes no retardada asociada a la primera señal de entrada se combina con la segunda señal de componentes retardada asociada a la segunda señal de entrada, donde la señal de componentes no retardada asociada a la segunda señal de entrada se combina con la primera señal de componentes retardada asociada a la primera señal de entrada, y donde cada una de las redes de acoplamiento cruzado (1001, 1002, 1003) se aplica sobre un respectivo canal de datos individual de la pluralidad de canales de datos individuales dentro de una banda base digital (200) de la estación de base.
