Abstract
UN SISTEMA DE COMUNICACION DE LINEA DE DISTRIBUCION DE ENERGIA, PARA Y METODO DE, REDUCCION DE EFECTOS DE CANCELACION DE SEÑALES EN SITUACIONES A LO LARGO DE LA LINEA DE DISTRIBUCION (2) DEBIDO A ONDAS ESTACIONARIAS CAUSADAS POR REFLEXIONES DE UNA SEÑAL PORTADORA IMPRESA SOBRE LA LINEA DE DISTRIBUCION (2). UNA MISMA SEÑAL DE DATOS DE SALIDA SE MODULA SOBRE CADA UNA DE UNA PLURALIDAD DE SEÑALES PORTADORAS (40, 42, 44) QUE TIENEN DIFERENTES FRECUENCIAS. LAS FRECUENCIAS DE SEÑALES PORTADORAS SON ELEGIDAS DE MANERA QUE TODAS LAS SEÑALES PORTADORAS (40, 42, 44) NO EXPERIMENTEN CANCELACION DE SEÑAL EN UNA MISMA SITUACION SOBRE LA LINEA DE DISTRIBUCION (2). LAS SEÑALES PORTADORAS MODULADAS (40, 42, 44) SE IMPRIMEN SIMULTANEMANETE SOBRE LA LINEA DE DISTRIBUCION (2) PARA LA TRANSMISION A SITUACIONES REMOTAS (4), CON LO QUE SE ASEGURA LA RECEPCION DE LA SEÑAL DE DATOS DE SALIDA EN CADA SITUACION REMOTA (4).
