Abstract

DATOS DIGITALES (PARTICULARMENTE SEÑALES CODIFICADAS DE PROGRAMA DE TELEVISION) SON COMUNICADAS DESDE UN TRANSMISOR A UN RECEPTOR TERRESTRE POR CODIFICACION CONVOLUCIONAL DE LOS DATOS DENTRO DE UNA PRIMERA Y UNA SEGUNDA SEÑAL DURANTE DIFERENTES PERIODOS QUE REPRESENTAN UNA TASA DE SEÑAL 1/2. DURANTE LOS PERIODOS DIFERENTES, LAS DOS SEÑALES SON COMBINADAS Y PUNTEADAS EN UNA CORRIENTE EN SERIE DE UNIDADES DE INFORMACION DE PUNTOS PARA PRODUCIR UNA SEÑAL CODIFICADA CONVOLUCIONAL DE CORRECCION DE ERROR DELANTERA QUE TIENE UNA TASA MANUAL O AUTOMATICAMENTE SELECCIONADA, P. EJ. TASA DE 2/3 O 6/7. SIENDO LAS SEÑALES CODIFICADAS EN DIFERENTES TASAS VARIABLES TRANSMITIDAS EN MOMENTOS MUTUAMENTE EXCLUYENTES EN PRIMER Y SEGUNDO NIVELES DE ENERGIA PARA RECIBIR VIA SATELITE. EN LAS TASAS VARIABLES, CORRIENTES DE UNIDADES DE INFORMACION DIGITALIZADAS EN PARALELO SON DERIVADAS SIMULTANEAMENTE Y MODULAN SIMULTANEAMENTE EL PAR DE PORTADORES (QPSK) ORTOGONALES. EL METODO DE DIGITALIZACION MEJORADO ES CAPAZ DE MANIPULAR LA TOTALIDAD DE LOS CODIGOS OPTIMOS DIGITALIZADOS Y USA UN RELOJ DIGITAL, MULTIPLEXOR, FIFO, RAM, ROM Y FUENTE DE CONTROL DE TASA. EL RELOJ DIGITAL SE USA PARA DERIVAR UN PAR DE TRENES DE ONDA QUE COMPRENDEN LAS UNIDADES DE INFORMACION SECUENCIALES DE LOS CANALES I Y Q Y UNIDADES DE INFORMACION FICTICIA INSERTADAS DENTRO DE LA SEÑAL SERIE. EL RECEPTOR RESPONDE AL PORTADOR QPSK Y DERIVA PRIMERO UNA SEÑAL SERIE QUE TIENE UNA CORRIENTE SECUENCIAL DE UNIDADES DE INFORMACION ALTERNANDO AMBAS UNIDADES DE INFORMACION SECUENCIALES I Y Q. ADEMAS ELLAS SON SECUENCIALMENTE RE-DISPUESTAS COMO SEÑALES I Y Q EN LAS MISMAS PARTICIONES DE TIEMPO.
