Abstract

La cantidad de usuarios y capacidad de datos de sistemas inalámbricos aumentan por el empleo de aparatos y de un método para aumentar la cantidad de códigos de dispersión disponibles en el sistema, proveyendo un mecanismo para reutilizar el código de dispersión ya asignado o para utilizar los códigos que pueden correlacionarse con aquellos que ya se están utilizando dentro del mismo sector/célula. Esto, a su vez, provee un aumento de capacidad proporcional a la cantidad de antenas de estación base (BS) agregadas a cada célula. Una técnica de dirección nula de antena para asignación de códigos mantiene las propiedades de correlación cruzada de los códigos solamente para el usuario deseado y para obtener una ganancia en mejoramiento de capacidad.
