Abstract

PARA DETERMINAR PARAMETROS DE CALIDAD DE UNA VIA DE TRANSMISION (SUT) SE INSERTA UNA SEÑAL DE MEDICION (DSS) EN UN FLUJO DE DATOS (1) CON ESTRUCTURA CELULAR, PRESENTADO CADA CELULA UN CAMPO UTIL (20) OCUPABLE CON DATOS, Y SE EVALUA DESPUES DE PASAR POR LA VIA DE TRANSMISION (SUT). SEGUN LA INVENCION SE EMPLEA COMO SEÑAL DE MEDICION UNA SUCESION DE CELDAS DE TEST (T11, T12, T14, T15), CUYOS CAMPOS UTILES (20) ESTAN OCUPADOS CADA UNO DE ELLOS CON UNA RETICULA DE TEST (19) CONSISTENTE EN UN NUMERO DE DATOS BINARIOS (BITS), CORRESPONDIENDO APROXIMADAMENTE A UN IMPULSO DIRAC LA FUNCION DE AUTOCORRELACION DE LA RETICULA DE TEST (19) Y ESTANDO VARIADA SIN REPETICIONES, DENTRO DE LA SERIE DE CELDAS DE TEST (T11, T12, T13, T14, T15), LA POSICION DE LA RETICULA DE TEST (19) EN LOS CAMPOS UTILES (20) DE LAS CELULAS DE TEST (T11, T12, T13, T14, T15); CADA CELULA DEL FLUJO DE DATOS (1) ES CORRELACIONADA DESPUES DE PASAR POR LA VIA DE TRANSMISION (SUT) CON UNA RETICULA DE REFERENCIA (34), QUE ES IDENTICAA LA RETICULA DE TEST (19) O INVERSA A TAL RETICULA. EL MAXIMO (M) DE LA FUNCION DE CORRELACION CRUZADA OBTENIDA ES EVALUADA EN FUNCION DE SU POSICION (N) RESPECTO AL PRINCIPIO (A) DE LA CELULA CORRESPONDIENTE Y RESPECTO A SU ALTURA (H).
