Abstract

En la presente, se provee un método y un aparato para seleccionar tamanos de intercaladores para turbocodigos. Durante la operacion se recibe un bloque de informacion de tamano K. Se determina un tamano del intercalador K' relacionado con Kö, en donde Kö proviene de un conjunto de tamanos; en donde el conjunto de tamanos comprende Kö = ap x °, pmin<= p <= pmax; °min <= ° <= °max, en donde a es un entero y ° es un entero continuo entre °min y °max, p adopta valores enteros entre pmin y pmax, a>1, pmax> pmin, pmin>1. El bloque de informacion de tamano K se amortigua en un bloque de entrada de tamano K' mediante bits de relleno, de ser necesario. La codificacion se realiza mediante el bloque de entrada original y el bloque de entrada intercalado, a fin de obtener un bloque de palabras codigo mediante un turbocodificador. El bloque de palabras codigo se transmite a través del canal.
