Abstract
A source-channel coding scheme in which source messages are assigned to two classes and encoded using a channel code that depends on the class index is studied. A low-complexity implementation with two quasi-cyclic LDPC codes with belief-propagation decoding achieves a better frame error rate than optimized separate coding. The coding gain obtained by simulation is consistent with the theoretical gain.
