A Decision Feedback Based Scheme for Slepian-Wolf Coding of sources with   Hidden Markov Correlation
  We consider the problem of compression of two memoryless binary sources, the correlation between which is defined by a Hidden Markov Model (HMM). We propose a Decision Feedback (DF) based scheme which when used with low density parity check codes results in compression close to the Slepian Wolf limits.
