The residual redundancy contained in the source coding output symbols can be used by the channel decoder to provide extra error protection. A joint source/channel coding scheme which employs nonbinary turbo codes over rings to exploit the residual redundancy of source coding output is investigated. Simulation results on codebook-excited linear predictive coded speech and differential pulse code modulation coded image transmissions over noisy channels are presented.
