Abstract

Un dispositivo de comunicaciones para separar senales fuente proporcionadas por M fuentes de senal incluye un arreglo de antena que comprende N elementos de antena para recibir al menos N diferentes sumas de las M senales fuente. Se conecta un modulo de en face y cuadratura respectivo corriente abajo a cada elemento de antena para separar cada una de las N diferentes sumas de las M senales fuente recibidas de este modo en el conjunto de componentes de en face y cuadratura. Un procesador de separacion a ciegas de senales forma una matriz de mezclado que comprende al menos 2N diferentes sumas de las M senales fuente, con cada conjunto de componentes de en face y cuadratura que proporciona dos entradas a la matriz de mezclado. La matriz de mezclado tiene un rango igual a 2N. Las senales fuente deseadas se separan de la matriz de mezclado por el procesador de separacion a ciegas de senales.
