Joint source and channel coding

{{Short description|Performing source coding and channel coding in a single operation}}

{{distinguish|joint encoding}}

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 and videotransmission.{{cite book |author1=M. R. Soleymani |author2=A. K.
