Abstract
EL PROCEDIMIENTO CONSISTE A NIVEL DE CADA RECEPTOR DEL SITEMA, EN COMPARAR (4) MODULO DEL NUMERO DE BITS CONTENIDOS EN UNA TRAMA DE DATOS TRANSMITIDOS, EL VALOR DE CADA UNO DE LOS BITS RECIBIDOS CON LOS VALORES PRESUPUESTADOS DE LOS BITS DE SINCRONIZACION, EN TOTALIZAR (9,1....9L) LOS RESULTADOS DE LAS COMPARACIONES EFECTUADAS EN CADA BITS Y EN MARCAR (3) EN LOS BITS RECIBIDAS LAS POSICIONES DE BIT MODULO EL NUMERO DE BITS CONTENIDOS EN UNA TRAMA, PARA LOS CUALES LOS TOTALES OBTENIDOS SON SUPERIORES A UN VALOR DE UMBRAL (S) AJUSTABLE, MODULO EL NUMERO DE BITS CONTENIDO EN UNA TRAMA, EN FUNCION DEL NUMERO DE COMPARACIONES ANTERIOEMENTE EFECTUADAS POR CADA BIT DE UNA TRAMA Y ADAPTADO EN FUNCION DE LAS PROBABILIDADES DE FALSAS ALARMAS Y DE NO DETECCION QUE CARACTERIZAN LAS TRANSMISION
