Abstract
Un vector de código que comprende 2N elementos de datos es generado en respuesta a N elementos de datos de entrada. Los primeros N elementos de datos del vector de código representan una réplica de los N elementos de datos de entrada, y los segundos N elementos de datos del vector de código comprenden N elementos de datos de paridad. La combinación y los primeros N elementos de datos y los segundos N elementos de datos forma un vector de código de Kerdock. El vector de código de Kerdock es decodificado para recuperar los N elementos de datos de entrada seleccionando uno de posibles 2N vectores de código de Kerdock como una mejor estimación del vector de código de Kerdock. El vector de Kerdock seleccionado comprende 2N elementos de datos, y solo los primeros N elementos de datos del vector de código de Kerdock seleccionado son utilizados como los N elementos de datos de entrada.
