Abstract :
This paper describes the optimization of LDPC codes for unequal error protection (UEP) transmission schemes. The method is based on a hierarchical optimization of the irregularity for each class within the codeword by maximizing the average data node degree with a given error sensitivity at a finite number of decoding iterations.
