On the UEP Capabilities of Several LDPC Construction Algorithms
Neele von Deetzen, Sara Sandberg · IEEE Transactions on Communications · 2010
This paper analyzes construction algorithms for low-density parity-check (LDPC) codes with respect to their unequal error protection (UEP) capabilities. We show that the choice of code construction algorithm highly affects the performance and UEP properties of LDPC codes with identical degree distributions. Our results provide an explanation to disagreements in earlier research.
