En el enlace descendente de un sistema CDMA se introducen multiples conjuntos de codigos para admitir más conexiones en cada célula. Los codigos después seasignan a diferentes usuarios, teniendo en cuenta la interferencia entre ellos. Lainterferenci a depende de las ganancias de antena, las potencias detransmision usadas y las correlaciones cruzadas entre los codigos. Estimando esos parámetros, se puede minimizar la interferencia en el proceso de asignacionde codigos. Como laasignacion de codig os y de conjunto de codigos a las zonas geográficas contenidas en una célula puede cambiar a lo largo del tiempo, sebrinda soporte al traspaso del servicio de codigos.Multiple sets of codes are introduced in the downlink of a CDMA system to support more connections in each cell. The codes are then assigned to different users, taking into account the interference between them. The interference depends on the antenna gains, the transmission powers used and the cross correlations between the codes. By estimating these parameters, interference in the code assignment process can be minimized. As the assignment of codes and code sets to the geographical areas contained in a cell may change over time, support for the transfer of the code service is provided.
