Abstract

EL DOMINIO DE LA INVENCION ES EL DE LA DIFUSION DE DATOS NUMERICOS DESTINADOS A SER RECIBIDOS SOBRE TODO POR MOVILES QUE CIRCULAN EN MEDIO URBANO, ES DECIR EN PRESENCIA DE PARASITOS Y DE INTERFERENCIA, Y EN CONDICIONES DE MULTIPROPAGACION (PROCESOS DE RAYLEIGH). LA INVENCION CONCIERNE A UN PROCESO DE DIFUSION NUMERICA EN EL CUAL LOS DATOS ESTAN REPARTIDOS EN FORMA DE ELEMENTOS NUMERICOS EN EL ESPACIO FRECUENCIA F MISION DE TRAMAS DE SIMBOLOS CONSTITUIDOS CADA UNO POR UN MULTIPLEX DE FRECUENCIAS PORTADORAS ORTOGONALES MODULADAS POR UNA SERIE DE ELEMENTOS NUMERICOS, Y DIFUNDIDAS SIMULTANEAMENTE SOBRE J VIAS PARALELAS, LA MODULACION ES UNA MODULACION DE GASES CON CUATRO ESTADOS DE FASE, CADA FRECUENCIA PORTADORA DE DICHO MULTIPLEX ESTA MODULADA POR UN PAR DE ELEMENTOS NUMERICOS. DICHOS PARES DE ELEMENTOS NUMERICOS ESTAN CONSTITUIDOS A PARTIR DE UNA SECUENCIA FUENTE DE ELEMENTOS NUMERICOS QUE CONSTITUYEN PAQUETES DE 2J ELEMENTOS CONSECUTIVOS EN DICHA SECUENCIA FUENTE, Y QUE ASOCIAN ELEMENTOS DOS A DOS EN CADA PAQUETE SEGUN UN CRITERIO DE MAXIMIZACION DE DISPERSION DE LOS ELEMENTOS NUMERICOS ADYACENTES DE LA SECUENCIA FUENTE. LOS MODOS DE ENTRELAZAMIENTO FRECUENCIAL Y TEMPORAL ESTAN IGUALMENTE PRESENTES.
