Abstract

El radio de acceso multiple por division de codigo de banda dual de la presente invencion opera en varias frecuencias en forma simultánea, ya sea para recibir o transmitir. La trayectoria de transmision opera dividiendo la trayectoria de frecuencia intermedia de transmision (IF) (103) y mezclando la IF con dos frecuencias de transmision diferentes, utilizando dos sintetizadores de frecuencia (140 y 145). La trayectoria de recepcion (104) tiene dos canales RF (116 y 117) que se mezclan con las frecuencias generadas por los sintetizadores (140 y 145) y se suman en una tira IF. De esta manera el radio de la presente invencion puede efectuar una transferencia de transmision suave entre frecuencias, mientras se comunica simultáneamente con las dos estaciones base. Otras trayectorias de mezclado y otros sintetizadores pueden adicionarse si se desea tener comunicacion con más de dos estaciones base en forma simultánea.
