Abstract

La presente se refiere a los métodos para asignar codigos de dispersion a las conexiones de enlace directo con velocidad de bits variable en los sistemasde comunicacion DS-CDMA. Se le asigna a una primera conexion una primera cantidad de codigos (x)desde un primer conjunto (S1) de codigos ortogonales. Se leasigna a una segunda conexion una segunda cantidad de codigos (y). Se toma una primera parte (y-k1) de la segunda cantidad de codigos (y) desde el primerconjunto (S1) de codigos ortogonales.Se toma un segunda parte (k1) de la segunda cantidad de codigos (y) desde un segundo conjunto (S2) de codigos ortogonalesque es no-ortogonal al primer conjunto (S1)
