Abstract

EN UN PROCEDIMIENTO PARA LA TRANSMISION DE SEÑALES DE DATOS ENTRE UN EQUIPO (3) FIJO Y UN EQUIPO (4) DE UN VEHICULO, DONDE LAS SEÑALES DE DATOS SON ENVIADAS EN FORMA DE MODULACION DE AMPLITUD, SE EVITA EL PUENTE DE SEÑALES POR MEDIO DE UN TENDIDO DE MULTIPLES VIAS DE TAL MODO QUE LA EMISION DE LA SEÑAL (ASK) DE DATOS SE CONSIGUE CON ONDAS POLARIZADAS CIRCULARES, QUE SON UTILIZADAS EN EL EQUIPO RECEPTOR DEL EQUIPO (4) DEL VEHICULO PARA POLARIZACION DIFERENTE DE LA ONDA RECIBIDA Y DE FORMA QUE LAS SEÑALES DEL EQUIPO DE RECEPCION SE DEMODULAN DE FORMA SEPARADA Y SON ADICIONADAS A CONTINUACION.
