Abstract

Un receptor dirigido, distribuido que utiliza una diversidad de usuarios multiples, provisto por la distribucion del receptor; se tiene ventaja de las variaciones no correlacionadas conforme transcurre el tiempo en la condicion de los enlaces de comunicacion entre un trasmisor comun y varios usuarios; entre mayor sea la variacion en la calidad de un enlace en particular conforme transcurre el tiempo, mayor sera el incremento en rendimiento de sistema total provisto; una metrica de programacion (o metrica programadora) representa la calidad instantanea del enlace de comunicacion entre cada usuario y el transmisor con respecto a la calidad promedio del enlace alternativamente, la metrica programadora representa la condicion del canal instantaneo con respecto al rendimiento de los datos promedio sobre ese canal; la estacion de transmision comun utiliza la metrica programadora para comparar directamente la conveniencia de otorgar cada acceso de canal con la conveniencia de otorgar cada otro acceso de canal; a los usuarios con enlaces que tengan la mayor metrica programadora, se les da acceso a esos canales.
