Abstract

SE PROPONE UN PROCEDIMIENTO QUE SIRVE PARA LA TRANSMISION POR TIERRA DE UNA SEÑAL DIGITAL COMO MINIMO, EN ESPECIAL DE UNA SEÑAL DIGITAL DE RADIO Y/O DE RADIOTELEVISION. CON ESTE PROCEDIMIENTO UNA SEÑAL DIGITAL COMO MINIMO, CUYO VOLUMEN DE DATOS HA SIDO REDUCIDO MEDIANTE CODIFICACION, SE MODULA PREFERENTEMENTE POR EL METODO OFDM Y SE TRASLADA A LA POSICION DE FRECUENCIA DE UN CANAL COMO MINIMO (31), QUE SEA ADYACENTE COMO MINIMO A UN CANAL (30, 32) OCUPADO O DESOCUPADO PARA LA TRANSMISION DE UNA SEÑAL DE RADIOTELEVISION ANALOGICA Y SE EMITE EN ESTA POSICION DE FRECUENCIA. EL MARGEN DINAMICO Y LA AMPLITUD DEL ESPECTRO (41) DE UNA SEÑAL DIGITAL COMO MINIMO TIENE QUE SER INFERIOR A UN VALOR DETERMINADO QUE SEA CLARAMENTE INFERIOR AL MARGEN DINAMICO O A LA AMPLITUD DE LA PORTADORA DE IMAGEN DEL ESPECTRO (35, 36) DE LA SEÑAL DE RADIOTELEVISION ANALOGICA, PARA QUE SOLO APAREZCA UNA PEQUEÑA INTERMODULACION O MODULACION CRUZADA CON OTRAS SEÑALES DIGITALES O ANALOGICAS DE OTROS CANALES. EL ESPECTRO (41) DE UNA SEÑAL DIGITAL COMO MINIMO SE TRANSMITE POR SEPARADO A PARTIR DE COMO MINIMO UN CANAL ADYACENTE (30, 32) MEDIANTE UN ESPACIADO DE FRECUENCIA DE PROTECCION (45). EN LA TRANSMISION DE VARIAS SEÑALES DIGITALES POR UN CANAL (31) COMO MINIMO, SE TRANSMITEN LAS GAMAS DE FRECUENCIA DE DOS SEÑALES DIGITALES COMO MINIMO, SEPARADAS ENTRE SI POR UNA DISTANCIA PROTECTORA (50).
