Abstract
Procedimiento para la transmisión velada de señales de telecomunicación, caracterizado porque se integran en un procedimiento los métodos conocidos en sí, de una cuadriculación de tiempo o intercambio de bandas de frecuencia, porque para ello las señales de comunicación del lado del emisor, dentro de un intervalo de tiempo, que se repite, se subdividen en un número (n) de elementos de tiempo y, dentro de un sector de banda de frecuencia, se subdividen en un número (m) de bandas de frecuencia parcial, porque el bloque de comunicaciones, caracterizado por el sector de tiempo, que se repite, forma una matriz (n.m) y un número de (n.m) elementos de banda de frecuencia parcial-tiempo.
