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.

Progressive transmission of images using MAP detection over channels with memory
TL;DR: A new maximum a posteriori (MAP) detector is proposed, without the need for explicit channel coding, to lessen the impact of communication channel errors on compressed image sources and the robustness of the proposed MAP detector's performance to estimation errors is studied.

The design of joint source and channel trellis waveform coders
Ender Ayanoglu,Robert M. Gray +1 more
TL;DR: The generalized Lloyd algorithm is applied to the design of joint source and channel trellis waveform coders to encode discrete-time continuous-amplitude stationary and ergodic sources operating over discrete memoryless noisy channels and it is observed that the jointly optimized codes achieve performance close to or better than that of separately optimized tandem codes of the same constraint length.

Combined Source-Channel Coding of Images
J. W. Modestino,D. G. Daut +1 more
TL;DR: A combined source-channel coding approach is described for the encoding, transmission and remote reconstruction of image data, resulting in a relatively robust design which is reasonably insensitive to channel errors and yet provides performance approaching the rate-distortion bound.
