Abstract

Se describen sistemas y métodos para mejorar la diversidad espacial de canal en un sistema de antenas múltiples (MAS) con trasmisiones de usuarios múltiples (MU) ("MU-MAS") explotando los indicadores de selectividad de canal. Los métodos propuestos son: i) selección de antena; ii) selección de usuario; iii) equilibrio de potencia de trasmisión. Se muestra que los tres métodos, o cualquier combinación de ellos, proveen ganancias funcionales significativas en sistemas DIDO, en escenarios de propagación prácticos.
