Abstract
En algunas modalidades, un método recibe una primera señal que se envía en una primera dirección en una red. Las comunicaciones en la red son comunicaciones dúplex completas en una misma banda de frecuencia. La primera señal se amplifica en la primera dirección. El método entrena a un primer cancelador de eco para cancelar una primera señal de eco de la primera señal donde la primera señal de eco se recibe en una segunda dirección. Después de entrenar el primer cancelador de ecos, se habilita el primer cancelador de eco entrenado. El método recibe una segunda señal en la segunda dirección que se envía en la segunda dirección en la red. La segunda señal se amplifica en la segunda dirección. El método entrena a un segundo cancelador de eco para cancelar una segunda señal de eco recibida en la primera dirección de la segunda señal donde el primer cancelador de eco cancela la primera señal de eco que se recibe en la segunda dirección.
