Abstract

La presente se relaciona con un método para convertir u flujo de bit del usuario en un flujo de bit codificado por medio de un codigo de canal en donde el codigo de canal tiene una compresion d=1. Para asegurar una mejora en el desempeno de la deteccion de bit se impone una compresion adicional de r=2. Una ventaja adicional de tal codigo es una limitacion en la profundidad de rastreo hacia atrás de un detector de bit Viterbi. Basado en dos compresiones k, se revela la construccion de tales codigos d=1 y r=2.
