Abstract

Un Nodo B/estación base comprende una pluralidad de antenas para recibir senales de usuario y un buscador de trayectoria. El buscador de trayectoria comprende un conjunto de correlacionadores. Cada correlacionador del conjunto de correlacionadores correlaciona un código de usuario ingresado con una salida de antena ingresada. Un controlador de antena acopla selectivamente una salida de una antena de la pluralidad de antenas a una entrada de cada una.
