Abstract

METODO DE SINCRONISMO DE CUADROS DE UN SISTEMA DE COMUNICACION DIGITAL MULTIPLEX POR DIVISION DE TIEMPO. CONSTA DE LAS SIGUIENTES OPERACIONES: 1) COMPARAR CADA BITIO DE UNA SECUENCIA DE N INTERVALOS SELECTORES CONSECUTIVOS CON UN BITIO DE LA PAUTA DE SINCRONISMO, CUYO ORDEN NUMERICO ES IGUAL AL NUMERO DE VECES CONSECUTIVAS INMEDIATAMENTE PRECEDENTES QUE SE HA DETECTADO CONCORDANCIA DE BITIES EN ESA POSICION DE BITIO. 2) DETERMINAR, PARA CADA POSICION DE BITIO, SI EXISTE O NO CONCORDANCIA. 3) REGISTRAR PARA CADA POSICION DE BITIO QUE SE DETECTO CONCORDANCIA EN POSICION CONTIGUA. 4) DETECTAR EL NUMERO DE N VECES CONSECUTIVAS Y CONTIGUAS QUE SE DETECTO CONCORDANCIA DE BITIOS EN UNA POSICION DE BITIO SITUADO EN LA POSICION DE BITIO DETERMINADA EN LA OPERACION ANTERIOR.
