Simulation Study of LDPC Codes for Nonuniform Sources With Side Information in Slepian-Wolf Coding

Free registration required

Executive Summary

The principles of distributed source coding or Slepian-Wolf coding, primarily employed for compression of correlated sources with side information, can also be used for reducing the encoder complexity of a single source. This effectively shifts the encoder complexity to the decoder. This exchange of computational complexities has opened up the door for many applications in wireless video and image communications. Till now, most of the research efforts are concentrated around compression of correlated sources which are uniformly distributed. But non-uniform sources are not uncommon in real world.
