Abstract
Se proporciona una unidad de radiocomunicación de modo dual (100, 102) para un sistema de comunicación digital de un controlador de error que incluye un codificador de detección de error (111) y un codificador de corrección de error anticipado (112), el cual codifica la señal de información de entrada (106) en un flujo de bit de datos protegidos contra error (114). Además, la unidad de comunicación (102) incluye un selector de modo el cual permite el uso de tanto el codificador de detector de error (111) como del codificador de corrección de error anticipado (112), usando con un modo particular de operación de la unidad de comunicación (102). Adicionalmente, la correspondiente unidad de radiocomunicación de modo dual (100, 104) se proporciona con un controlador de error para generar muestras de señal de información estimada muestra (208) de acuerdo a un grupo de algoritmos consistente en algoritmo de detección de error (201) o un algoritmo de corrección de error (202). En adición, la unidad de comunicación correspondiente (104) incluye un selector de modo para recibir una señal (140) de acuerdo a un algoritmo particular de un grupo de algoritmos (201, 202) que está asociado con un modo particular de operación que corresponde a la unidad de comunicación (104).
