Abstract

Los datos que se van a transmitir sobre un canal desde un trasmisor hacia un receptor se codifican para obtener una palabra clave. La palabra clave se define por una pluralidad de nodos variables asociados con una pluralidad de nodos de verificación de una gráfica bipartita que representa el código. La palabra clave se trasmite sobre el canal tal que ciertos nodos variables se trasmiten antes de otros nodos variables. Los ciertos nodos variables se asocian con un subconjunto de los nodos de verificación de la gráfica bipartita y definen un subpalabra clave conocida en el receptor. En el receptor, se estima una capacidad de descodificación de la palabra clave trasmitida usando la subpalabra clave antes de recibir todos los nodos variables de la palabra clave.
