Joint source and channel coding
- Joint source and channel coding
In information theory, joint source–channel coding is the encoding of a redundant information source for transmission over a noisy channel, and the corresponding decoding, using a single code instead of the more conventional steps of source coding followed by channel coding.
Joint source–channel coding has been proposed and implemented for a variety of situations, including speech [cite book | chapter = Vector Trellis Quantization for Noisy Channels | title = Advances in Speech Coding | author = M.
