Resumen
Uno de los retos en el diseño de esquemas de detección para sistemas MIMO con un gran número
de antenas en sistemas de comunicaciones inalámbricas, conocido como L-MIMO (Large MIMO), es
lograr algoritmos de detección eficientes de baja complejidad para hacer viable su implementación
real. Este artículo presenta los resultados logrados con un esquema basado en el algoritmo de
propagación de esperanzas, comparándolo por medio de simulación con detectores lineales de
referencia que se tienen en la literatura, demostrando que a partir de configuraciones 8x8 se logra
una mejor relación desempeño-complejidad, consiguiendo disminuir notoriamente el tiempo de
ejecución en evaluaciones que se hacen hasta L-MIMO 64x64.
PALABRAS CLAVES: L-MIMO, Propagación de Esperanzas, Detección, Baja Complejidad,
Comunicaciones Inalámbricas.
