New iterative decoding of variable length codes with turbo-codes

X. Jaspar, L. Vandendorpe
2004 2004 IEEE International Conference on Communications (IEEE Cat. No.04CH37577)  
The performance due to the turbo-code alone leads to an increased freedom in the VLC design -depending on the application -, and suggests to revisit the VLC distance criteria investigated in [5].  ...  The decoding algorithm for this three SISO modules scheme is briefly presented in the framework of Bayesian networks.  ...  Indeed everything depends on the statistical distribution of the source at stake.

A Memetic Algorithm and a Solution Archive for the Rooted Delay-Constrained Minimum Spanning Tree Problem [chapter]

Mario Ruthmair, Günther R. Raidl
2012 Lecture Notes in Computer Science  
The memetic algorithm is based on a specialized solution representation and a simple and effective decoding mechanism.  ...  The first check is performed immediately before decoding the delay array and improving the solution to prevent wasting time on revisits, the second after encoding the solution again to preserve diversity  ...  In future work we want to adapt our decoding method to improve the quality of decoded solutions.  ...

Wyner-Ziv video coding: A review of the early architectures and further developments

Fernando Pereira, Catarina Brites, Joao Ascenso, Marco Tagliasacchi
2008 2008 IEEE International Conference on Multimedia and Expo  
Turbo Decoding: Once the side information DCT coefficients and the residual statistics for a given DCT coefficients band are known, each bitplane is turbo decoded (starting from the MSB one).  ...  In the latter approach, it is easier to accommodate coding adaptability to address the highly non-stationary statistics of video signals. 2. Decoder rate control versus encoder rate control.  ...

Bit-interleaved coded modulation revisited: A mismatched decoding perspective

Alfonso Martinez, Albert Guillen i Fabregas, Giuseppe Caire, Frans Willems
2008 2008 IEEE International Symposium on Information Theory  
We revisit the information-theoretic analysis of bitinterleaved coded modulation (BICM) by modeling the BICM decoder as a mismatched decoder.  ...  The mismatched-decoding model is well-defined for finite, yet arbitrary, block lengths, and captures the channel memory among the bits belonging to the same symbol.  ...  In general, these bit metrics are statistically dependent and the decoder uses a metric proportional to the product of the marginals p j (y|b).  ...
