It was understood that Slepian–Wolf coding is closely related to channel coding in 1974, and after about 30 years, practical DSC started to be implemented by different channel codes. The motivation behind the use of channel codes is from two sources case, the correlation between input sources can be modeled as a virtual channel which has input as source and output as source .
