Abstract
UNA ESTACION DE RADIOTRANSMISION (12) TRANSMITE UN DATO DIGITAL A UNA PREDETERMINADA VELOCIDAD HASTA UNA ESTACION RECEPTORA (18). LA ESTACION RECEPTORA ESTA CONTROLADA POR UN CIRCUITO TEMPORIZADOR (22) QUE RECONOCE UN CODIGO DE AUTORIZACION PREDETERMINADO. LOS DATOS DIGITALES SE TRANSFORMAN EN SECUENCIAS DE BIT Y CADA SECUENCIA CONTIENE UN PRIMER GRUPO DE BITS (BR) PARA SINCRONIZAR EL CIRCUITO DE TEMPORIZACION Y LA VELOCIDAD DE TRANSMISION DE LOS DATOS. ESTE PRIMER GRUPO DE BITS VA SEGUIDO POR UN SEGUNDO GRUPO DE BITS (SC) QUE INCLUYE EL CODIGO DE AUTORIZACION. EL RECONOCIMIENTO DEL CODIGO DE AUTORIZACION HACE POSIBLE QUE LA ESTACION RECEPTORA (18) RECIBA Y PROCESE LA INFORMACION TRANSMITIDA. EL CODIGO DE AUTORIZACION SE DERIVA DE UNA SECUENCIA DE BITS DE CEROS Y UNOS LOGICOS Y CIERTOS BITS DE DIFERENCIA SON ALTERADOR PARA FORMAR GRUPOS DE 3 BITS (111,000). CADA GRUPO DE TRES BITS TIENE HASTA DOS PARES ADYACENTES DE BITS SIMILARES Y OPUESTOS (10,01). LOS GRUPOS DE BITS SIMILARES SE DISPONENEN UNA PRIMERA PARTE DEL SEGUNDO GRUPO (SC) DE FORMA QUE LAS OPORTUNIDADES DE UN RECONOCIMIENTO INCORRECTO SE MINIMICEN Y LA SINCRONIZACION CONSEGUIDA POR EL PRIMER GRUPO DE BITS (BR) PERMANEZCA INALTERADA.
