Abstract

Un metodo para asignar elementos de rastreo que lista de incluye la clasificacion de una asignaciones potenciales de acuerdo con un criterio de diversidad. En un ejemplo, una lista de casos de senal recibida es clasificada primero de acuerdo con una medida de energia y luego es clasificada nuevamente de acuerdo con el criterio de diversidad. En una modalidad adicional, un elemento de desmodulacion puede ser marcado disponible para la asignacion todavia continua para producir simbolos desmodulados en un estado asegurado. Se explican las aplicaciones para una estacion movil de un sistema CDMA para telefonia celular.
