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 DE LA SUCESION DE COEFICIENTES (1). LA SUCESION DE COEFICIENTES SE CONVIERTE EN UNA SEÑAL DE EMISION (3) MODULADA CON SALTO DE FRECUENCIA. POR PARTE DEL RECEPTOR SE EFECTUA PRIMERO CON AYUDA DE UN CIRCUITO PLL (5) UNA RECONVERSION EN UNA TENSION DE ETAPAS MULTIPLES Y A CONTINUACION 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 CON ELEVADA TASA DE DATOS Y CANAL DE TRANSMISION FUERTEMENTE PERTURBADO, CON SEGURIDAD Y SIN SINCRONIZACIONCON LA FRECUENCIA DE LA RED.
