Abstract

Un dispositivo de comunicaciones para separar senales de fuente proporcionadas M fuentes de senal incluye un arreglo de antena que comprende N en elementos de antena para recibir al menos N diferentes sumas de las M senales fuente, con N y M que son mayores que 1. Los N elementos de antena que incluyen al menos un elemento de antena para recibir al menos una de las N diferentes sumas de las M senales de fuente, y al menos dos elementos de antena correlacionados para recibir al menos dos de las N diferentes sumas de las M senales de fuente. Al menos dos elementos de antena correlacionados estan sin correlacionar con al menos un elemento de antena: se conecta un receptor al arreglo de antena. Se conecta un procesador de separacion a ciegas de senales al receptor para formar una matriz de mezclado que comprende al menos N de diferentes sumas de las de M senales fuente, y para separar las senales deseadas de fuente de la matriz de mezclado. La matriz de mezclado tiene un rango igual al menos N.
