METHOD, BASE STATION AND SUBSCRIBER STATION FOR CHANNEL CODING IN A GSM MOBILE RADIOTELEPHONE SYSTEM

摘要

The invention relates to the use of recursive systematic codes (RSC) for channel coding in GSM mobile radiotelephone systems. Contrary to previous notions, RSC codes based on hardware that has been installed in existing GSM mobile radiotelephone systems can now also be used. The RSC codes can be introduced as part of the introduction of an adaptive multirate coder (AMR).
