Abstract :
For joint source channel coding we extend the concept of incremental redundancy to a combination of decremental and incremental redundancy in a parallel concatenated turbo scheme. Even for compression only the new scheme outperforms Lempel-Ziv compression, but has many advantages in adaptive type II FEC/ARQ systems for the transmission over noisy channels.
