Abstract

Un aparato de radiocomunicacion (100) recibe una senal constituida por primera, segunda y tercera palabras que contienen datos de mensaje y de correccion de errores. Las segunda y tercera palabras son palabras repetidas asociadas con la primera. Un procesador (120) compara cada bit de correspondencia en las primera, segunda y tercera palabras, determina, para cada bit correspondiente, cual de entre los valores primero y segundo del bit es un valor mayoritario del bit, y genera una cuarta palabra que incluye un bit por cada bit correspondiente. Cada bit de la cuarta palabra tiene un valor equivalente a valor mayoritario del bit correspondiente. Circuitos de correccion de errores (135) efectuan la correccion de errores en las primera , segunda, tercera y cuarta palabras, utilizando la informacion para correccion de errores. El procesador (120) selecciona luego para su presentacion los datos de mensaje contenidos en una de las primera, segunda, tercera y cuarta palabras, cuando por lo menos una de entre las primera, segunda, tercera y cuarta palabras ha sido corregida.
