Abstract

UN SISTEMA DE TRANSMISION DIRECTA VIA SATELITE ES PROPORCIONADO EL CUAL ENSAMBLA BITS DE PROGRAMAS DE TRANSMISION EN INCREMENTOS DE FRECUENCIA PRINCIPAL, VARIOS DE LOS CUALES ESTAN ENSAMBLADOS EN UN CUADRO. LOS CUADROS ESTAN DIVIDIDOS EN SIMBOLOS QUE SON DESMULTIPLEXADOS EN ALTERNOS DE UNA PLURALIDAD DE CANALES DE FRECUENCIA PRINCIPAL. LOS CANALES DE FRECUENCIA PRINCIPAL SON DESMULTIPLEXADOS EN UN NUMERO CORRESPONDIENTE DE FRECUENCIAS DE TRANSMISION PARA TRANSMISION A UN SATELITE. UN DESMULTIPLEXOR POLIFASE A BORDO SEPARA LAS SENALES DE ENLACE HACIA SATELITE EN CORRIENTES DE SIMBOLOS MULTIPLEXADAS POR DIVISION DE TIEMPO. UN DESMODULADOR DE DESPLAZAMIENTO DE FASE POR TECLADO A BORDO DESMODULA LOS SIMBOLOS EN DATOS DE BANDA DIGITAL. UN APARATO DE ALINEACION DE FRECUENCIAS A BORDO CORRIGE LAS DIFERENCIAS DE FRECUENCIAS DE RELOJ ENTRE UN RELOJ A BORDO Y LOS SIMBOLOS DE TRANSMISION. LA CARGA UTIL DEL SATELITE CONMUTA LOS SINBOLOS EN CORRIENTES DE DATOS MULTIPLEXADOS POR DIVISION DE TIEMPO (TDM) USANDO DOS MEMORIAS INTERMEDIAS DE ALTERNACION Y UN CONMUTADOR DE RUTA. LOS RECEPTORES PROCESAN LAS CORRIENTES TDM USANDO PREAMBULOS DE CUADRO MAESTRO Y CANALES DE CONTROL DE CUOTAS DE TIEMPO PROVISTOS ALLI EN ELLOS POR EL SATELITE, Y ENCABEZADORES DE CONTROL DE SERVICIOS (SCHs) PROVISTOS ALLI EN ELLOS POR LAS ESTACIONES DE TRANSMISION. LOSSCHs PROVEEN PARA DIRECCIONAMIENTO DE RECEPTORES PARTICULARES Y PARA SERVICIOS MULTIMEDIOS. UN SISTEMA DE MANEJO ES PROVISTO PARA MANEJAR Y CONTROLAR EL SATELITE Y LAS ESTACIONES DE TRANSMISION.
