Abstract

We develop asymptotic analysis of recently constructed unequal error protection (UEP) quasi-cyclic (QC) low-density parity-check (LDPC) codes by using density evolution and its Gaussian approximation in this paper. The proposed analysis can indeed yield different decoding thresholds for different protection levels. As verified by computer simulation, the coding gain differences between protection levels can also be well predicted.
