Abstract :
A VLSI architecture for a joint source and channel trellis coder is presented. For a noisy channel and low SNR, it can be more efficient to use a joint source and channel coding scheme than a tandem system where source and channel coders are designed separately. In the architecture presented in this paper, we show that the trade off complexity-performance, in terms of source distortion, outperforms the classical tandem scheme
