Abstract
One of Shannon's many fundamental contributions was his result that source coding and channel coding can be implemented separately without any loss of optimality. However, the assumption underlying this result may at times be violated in practice. Various joint source/channel coding approaches have been developed for handling such situations. A MAP approach to joint source/channel coding has been proposed which uses a MAP decoder and a modification of the source coder to provide error correction. We present various implementation strategies for this approach and provide results for an image coding application.Keywords
