Abstract

SE PRESENTA UN METODO PARA DETERMINAR EL TIEMPO DE RECEPCION DE UNA SEÑAL CONTENIENDO UN CODIGO PREDETERMINADO, POR EJEMPLO UN UN CODIGO "BARKER". EL CODIGO PUEDE ESTAR PRESENTE AL COMIENZO DE UN TELEGRAMA QUE SERA RECIBIDO POR LA SEÑAL SE CORRELACIONA CON UN CODIGO DE CORRESPONDENCIA ALMACENADO EN LA MEMORIA. LA CORRELACION SE LLEVA A CABO EN DIFERENTES ESPACIOS DE TIEMPO. ESTO PRODUCE UNA CURVA DE CORRELACION (FIG.2). LA CUSPIDE REPRESENTA LA CORRELACION DEL PICO. EL TIEMPO DE LA CORRELACION OPTIMA SE DETERMINA EXTRAPOLANDO LOS LADOS CON LA CUSPIDE. EL INVENTO TAMBIEN SUMINISTRA UN DETECTOR DE CRUCE CERO PARA EVENTOS DE CRUCE CERO MEDIANTE EL CUAL UN TIEMPO SUFICIENTEMENTE EXACTO DE RECEPCION DEL CODIGO HACE POSIBLE UNA CORRELACION SIGNIFICATIVA.
