Abstract
The residual redundancy contained in the source coding output symbols can b e used by the channel decoder to provide extra error protection. A joint so urce/channel coding scheme which employs nonbinary turbo codes over rings t o exploit the residual redundancy of source coding output is investigated. Simulation results on codebook-excited linear predictive coded speech and d ifferential pulse code modulation coded image transmissions over noisy chan nels are presented.
