Abstract

Una disposicion de comunicaciones de terminal de abertura muy pequena para comunicacion vía satélite, utiliza codificacion concatenada paralela en susenlaces interno o externo, o ambos. Para bloques cortos de datos, se usan codigosconvolucion ales unidos en la cola, sistemáticos, no repetitivos. Parabloques de datos más largos se usan codigos convolucionales sistemáticos repetitivos. Estas técnicas de codificacion concatenada paralela se usan conconjuncion conmodulacion de espectr o extendido, para proporcionar una disposicion de comunicaciones de terminal de abertura muy pequena que cumplacon las regulaciones de la Comision Federa de Comunicaciones acerca de la densidad espectral depotencia total de las senal es transmitidas, y que mitigala interferencia desde satélites adyacentes.
