Although the performance of LDPC codes transmitted over binary-input memoryless channels is known and well studied in the literature, a formal proof of their potential to achieve channel capacity is still lacking. Moreover, the application of LDPC codes to generic memoryless channels, and, in ...
Les codes LDPC (Low Density Parity Check codes pour codes à faible densité) forment une classe de codes en bloc qui se caractérisent par une matrice de contrôle creuse. Ils ont été décrits pour la première fois dans la...

Lastly, we address the error propagation problem inherent in SC-LDPC codes by deploying a complementary weight set, which is activated when an error is detected in the previous window. This adaptive decoding strategy effectively mitigates error propagation without requiring modifications to the code ...
