Abstract

La invencion se refiere a un sistema para modular una senal de informacion en un sistema de telecomunicaciones. El sistema de telecomunicaciones hace uso de codigos de ensanchamiento en la modulacion a fin de discriminar entre las senales del usuario. Los codigos se asignan para los pedidos entrantes mediante la seleccion entre una o más estructuras de codigos de diferentes velocidades de transferencia de bits. El sistema se caracteriza por los pasos de: notar la velocidad de transferencia de bits de un codigo que se habrá de asignar para un pedido entrante; determinar la disponibilidad de los diferentes codigos que tiene la velocidad de transferencia de bits deseada; y asignar un codigo de acuerdo con normas pre-seleccionadas a través de considerar la disponibilidad de diferentes codigos de manera que conduzca a un uso optimo de la o las estructuras de codigos. El aparato de la invencion comprende los medios para poner en práctica el sistema de la invencion. El algoritmo de la invencion pone en práctica el sistema de asignacion de la invencion en la forma de un programa de computacion de acuerdo con ciertas normas.
