Abstract

PROCEDIMIENTO DE EMISION DE ONDAS MODULADAS QUE UTILIZA SIMULTANEAMENTE UNA PLURALIDAD DE FRECUENCIAS Y QUE CONSTA DE ETAPAS SUCESIVAS DE EMISION DE SIMBOLOS DURANTE UN TIEMPO DETERMINADO T + T, SIENDO DOS FRECUENCIAS DE EMISION DISTANTES DE 1/T, SIENDO T EL INTERVALO UTIL DE EMISION Y T EL INTERVALO DE TRANSICION. SE EMITEN SEÑALES DE SINCRONIZACION QUE PERMITEN EN LA RECEPCION EL MUESTREO DE LA SEÑAL DURANTE UNOS INTERVALOS UTILES DE EMISION DE DURACION T CON EL FIN DE HACER ORTOGONALES UNOS CANALES CORRESPONDIENTES A LAS DIVERSAS FRECUENCIAS. EL INVENTO SE APLICA EN LA DIFUSION Y LA RECEPCION DE EMISIONES RADIOFONICAS Y DE TELEVISION, EN LOS DISPOSITIVOS DE RECEPCION DE INFORMACIONES ANALOGICAS Y/O NUMERICAS, EN LAS COMUNICACIONES TELEFONICAS ENTRE CENTRALES, EN LAS COMUNICACIONES TELEFONICAS ENTRE RADIOTELEFONOS Y ESTACIONES DE COMUNICACIONES, EN LAS COMUNICACIONES RADIOELECTRICAS ENTRE ESTACIONES TERRESTRES Y SATELITES, EN LAS COMUNICACIONES ENTRE SATELITES, EN LAS COMUNICACIONES ACUSTICAS EN EL AIRE Y/O EN EL AGUA Y EN LA REALIZACION DE REDES LOCALES DE ORDENADORES. EL INVENTO ESTA ESPECIALMENTE BIEN ADAPTADO EN LAS EMISIONES RADIOFONICAS DE ALTA FIDELIDAD ASI COMO EN LA TELEVISION DE ALTA DEFINICION (HDTV EN TERMINOLOGIA ANGLOSAJONA), Y/O LA TELEVISION NUMERICA.
