Resumen

En este trabajo se describe la implementación de la técnica basada en multiplexación espacial D-BLAST sobre equipos de Radio Definida por Software (SDR); específicamente, utilizando el Universal Software Peripheral Radio (USRP) Ettus Research x310; con el objetivo de resolver el problema de diversidad espacial que tiene el esquema MIMO Alamouti, ya que no es posible aumentar el número de antenas del transmisor con respecto al receptor. El escenario de simulación fue en un ambiente de interior utilizando herramientas de programación gráfica con el Software de Comunicaciones Labview, logrando un diseño de codificación más robusto basado en la no linealidad de las ecuaciones matriciales, de esta manera, los efectos de la interferencia fueron mitigados a través de la redundancia de información debido al aumento de las antenas en el transmisor. Los resultados experimentales evaluados fueron la tasa de error de bit (BER) y la tasa de error de símbolo (SER) para determinar la eficacia de la diversidad espacial. La ganancia conseguida fue de unos 10dB y 7dB en MIMO 2×2 y MIMO 3×2 respectivamente, utilizando la técnica D-BLAST simétrica.
