Abstract

Verfahren zur Umsetzung von Eingangsbits auf Modulationssymbole, bei dem die Modulationssymbole Bitstellen aufweisen, welche sich zumindest teilweise hinsichtlich ihrer Kanalfehleranfälligkeit voneinander unterscheiden, bei dem mittels Generatorpolynomen aus den Eingangsbits faltungscodierte Eingangsbits generiert werden, denen jeweils ein Priorisierungswert zugeordnet wird, und bei dem die Abbildung der faltungscodierten Eingangsbits auf Bitstellen der Modulationssymbole unter Berücksichtigung der Kanalfehleranfälligkeit der Bitstellen der Modulationssymbole und des Priorisierungswertes des faltungscodierten Eingangsbits erfolgt.
