Titel:
Probabilistic Shaping with Low-Density Graph Codes and Message Passing
Abstract:
The compound LDGM/LDPC codes are shown to attain the information-theoretic limits of the Gelfand-Pinsker and Wyner-Ziv problems when optimal encoding and decoding are employed. The sparse and graphical structure of this code motivates it to be implemented with message passing algorithms. In this thesis, an encoding and decoding message passing algorithm is proposed for the compound code by inspiring the belief propagation and truthiness propagation algorithms. Initial simulations show that the e...     »
