Abstract

Un método de codificación y decodificación convolucional concatenado en paralelo utiliza códigos convolucionales sistemáticos no recurrentes deposicionamiento de bit en cola. El decoficador asociado utiliza iterativamente decodificación máxima aposteriori circular para producir salidas de decisiónduras y blandas. Esta disposición de codificación/decodificación da como resultado características de funcionamiento mejoradas para la corrección deerrores para mensajes cortos.
