Abstract: A joint source channel coder (JSCC) for image transmission over flat fading channels is presented. By letting the transmitter have information about the channel, and by letting the code-rate vary slightly around a target code-rate, it is shown how a robust image coder is obtained by using time discrete amplitude continuous symbols generated through the use of nonlinear dimension changing mappings. Due to their robustness these mappings are well suited for the changing conditions on a fading channel.
