Abstract

Se resuelve el problema de limitacion de codigos de canalizacion de enlace descendente encontrados en los sistemas celulares de espectro esparcido o CDMAusando codigos de un conjunto de codigos diferentes y no ortogonales cuando se opera en modo ain tervalos. Los conjuntos de codigos no ortogonales se puedenconstruir usando el mismo árbol de codigos de canalizacion, pero aplicando un codigo de aleatorizacion diferente.
