Abstract

LA INVENCION SE REFIERE A UN PROCESO PARA LA TRANSMISION DE DATOS POR MEDIO DE REDES DE DISTRIBUCION ELECTRICA, EN EL QUE SE EMPLEA UNA TECNICA DE SEPARACION DE BANDA. LA SEÑAL DE EMISION UTILIZADA SE GENERA CON EMPLEO DE COEFICIENTES DE UNA FUNCION DE AUTOCORRELACION ELEGIDA FAVORABLE CON ELEVADA RELACION DE MAXIMO PRINCIPAL A MAXIMO SECUNDARIO. LA MODULACION DE LA SEÑAL CON DATOS BINARIOS SE REALIZA POR LA CORRESPONDIENTE FIJACION DE POLARIDAD (1) DE LA SUCESION DE COEFICIENTES. SE EFECTUA UNA CONFORMACION DE LA SEÑAL POR EXPANSION (2), INTERPOLACION (3) Y MODULACION (4) ESPECIAL DE UNO O VARIOS CANALES, PARA TRANSFORMAR LA SEÑAL DE EMISION EN UNA FORMA FAVORABLE PARA LA TRANSMISION, QUE APROVECHE BIEN EL CANAL DE TRANSMISION DISPONIBLE RESPECTO AL ANCHO DE BANDA Y A LA ENERGIA DE EMISION. POR PARTE DEL RECEPTOR SE EFECTUA UNA RECEPCION EN CORRELACION (6), EN LA QUE LA FUNCION DE AUTOCORRELACION UTILIZADA SE ORIGINA COMO SEÑAL DE SALIDA, CUYO MAXIMO PRINCIPAL TAMBIEN SE PUEDE DETECTAR CONELEVADA TASA DE DATOS Y CANAL DE TRANSMISION FUERTEMENTE PERTURBADO, CON SEGURIDAD Y SIN SINCRONIZACION CON LA FRECUENCIA DE LA RED.
