Abstract

Los factores de variables de expansion y las transmisiones de multicodigos se acomodan en forma flexible por medio de la asignacion de codigos de expansionsegun las técnicas descriptas. Los codigos de expansion se asignan de manera tal que el canal de control sea ortogonal a todos los canales físicos en la senalde espectro de expansion. El balance de energía entre las ramas en fase (I) y la de cuadratura (Q) en el transmisor también derivan de la asignacion de canalesfísicos a las ramas apropiadas y la division de los canales físicos, cuando resulte necesario.
ARP980103329A 1997-07-11 1998-07-08 Transmisor que tiene una rama en fase (i) y una rama en cuadratura (q) para transmitir una senal de espectro de expansion, incluyendo por lo menos doscanales fisicos y metodo para asignar los codigos de expansion a una pluralidad de canales fisicos a ser transmitidos por dicho transmisor AR016313A1 (es)
