Abstract

Un sistema de radio difusión para transmitir simultáneamente señales desde una serie de puntos radio transmisores incluyendo impulsos transmisores de señal en una determinada onda portadora desde uno de dichos puntos, recibiendo los impulsos transmitidos en los otros puntos, produciendo un tren de impulsos de señales en cada uno de los otros puntos en distinta relación de fase con respecto a los impulsos recibidos, y transmitiendo en cada uno de los otros puntos producidos allí en dicha dada frecuencia portadora.
