Abstract
SISTEMA DE TRANSMISION DE DATOS CON ESPECTRO EXTENDIDO A TRAVES DE LA RED ELECTRICA. ESTE SISTEMA UTILIZA PARA LA GENERACION DE LOS DATOS, CODIGO Y PORTADORA EN EL EMISOR, RELOJES SINCRONIZADOS OBTENIDOS POR DIVISIONES SUCESIVAS DE UN UNICO OSCILADOR PATRON, REALIZANDOSE EN EL RECEPTOR LA SINCRONIZACION DE CODIGO, PORTADORA Y LA TEMPORIZACION DE BIT EN UNA UNICA OPERACION. PARA ELLO, EL CIRCUITO DE SINCRONIZACION DEL RECEPTOR UTILIZA COMO REFERENCIA LOCAL UNA SEÑAL COMPUESTA POR EL CODIGO SEUDOALEATORIO Y LA PORTADORA MULTIPLICADOS, CON LO QUE SE OBTIENE UNA FUNCION DE AUTOCORRELACION COMPLEJA QUE TIENE POR ENVOLVENTE LA FUNCION DE CORRELACION DEL CODIGO Y QUE PRESENTA UNA SERIE DE LOBULOS O PICOS. EL SEGUIMIENTO DE LA SEÑAL RECIBIDA SE REALIZA UTILIZANDO CINCO SEÑALES DE REFERENCIA, COMPUESTAS POR CODIGO Y PORTADORA DESFASADAS ENTRE SI, UNA PARA DEMODULAR, DOS PARA EL ENGANCHE DEL BUCLE Y OTRAS DOS PARA EL CIRCUITO DE ESTIMACION DE MAXIMO QUE PERMITE DETERMINAR SI EL LOBULO DE ENGANCHE ESEL PRINCIPAL.
