Abstract

Procedimiento de transmisión simultáneo en tiempo y frecuencia de múltiples comunicaciones de datos mediante modulaciones OFDM Que permite solucionar los problemas relativos a la interferencia producida entre equipos de comunicación de una misma tecnología pero pertenecientes a comunicaciones distintas que utilizan simultáneamente el mismo canal de comunicaciones en tiempo y frecuencia. Comprende modificar al menos uno de los parámetros de la señal de inicio. La ventaja principal de la invención es conseguir, de forma sencilla, que un equipo se sincronice correctamente con las señales que le llegan de su propia red mientras ignora las señales de menor potencia que son recibidas de otras redes que utilicen la misma o distinta tecnología, sin necesidad de realizar un complejo y costoso procesamiento en recepción.
