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 despropagador de codigos a los N elementos de antena para descodificar al menos N diferentes sumas de las M senales fuente. Cada una de las N diferentes sumas incluye k codigos para proporcionar k diferentes sumas de las M senales asociadas con las mismas. Un procesador de separacion a ciegas de senales forma una matriz de mezclado que comprende al menos kN diferentes sumas de las M senales fuente, y separa las senales fuente deseadas de la matriz de mezclado. La matriz de mezclado tiene un rango igual hasta kN.
