Universal Algorithms for Channel Decoding of Uncompressed Sources

Erik Ordentlich, Gadiel Seroussi, Sergio Verdu, Krishnamurthy Viswanathan
2008 IEEE Transactions on Information Theory  
This paper proposes several universal channel decoders that take advantage of the source redundancy without requiring prior knowledge of its statistics.  ...  In many applications, an uncompressed source stream is systematically encoded by a channel code (which ignores the source redundancy) for transmission over a discrete memoryless channel.  ...  ACKNOWLEDGMENT The authors would like to thank Marcelo Weinberger and Tsachy Weissman for discussions that led to this work.  ...

Universal lossless source controlled channel decoding for I.I.D. sequences

G.I. Shamir, Kai Xie
2005 IEEE Communications Letters  
We propose to integrate universal lossless source coding techniques into channel decoding of redundant sequences with unknown statistics to improve performance of Viterbi and turbo decoding.  ...  Messages coded and transmitted over a channel usually contain some redundancy which is not utilized by channel decoding techniques, especially if its governing statistical parameters are unknown.  ...  ACKNOWLEDGMENTS The authors gratefully acknowledge Shlomo Shamai and an anonymous reviewer for providing feedback that led to improving the simulation results and their presentation.  ...
