Abstract

El numero de usuarios (USUARIO A, USUARIO B) y la capacidad de datos (dA, dB) de sistema inalambricos (Fig. 1) se incrementan empleando un aparato y un metodo para incrementar el numero de codigos de propagacion (CA, CB) disponibles en el sistema proporcionando un mecanismo para reutilizar el codigo de propagacion ya asignado o utilizar los codigos que puedan correlacionarse con aquellos que ya estan siendo utilizados dentro del mismo sector/celula. Esto a su vez, proporciona una mejora en la capacidad proporcional al numero de antenas (1, 2, 3) de estacion base (BS) agregadas por cada celula. Una tecnica de control nulo para la asignacion de codigo mantiene las propiedades de correlacion de los codigos unicamente para el usuario deseado y para obtener una ganancia en la mejora de la capacidad.
