Short Blocklength Nonbinary Raptor-Like LDPC Coding Systems Design and Simulation by Jakub Hyla, Wojciech Sulek

“…Further exploration shows that, when the NB QC-RL-LDPC coding over Galois Field <inline-formula> <tex-math notation="LaTeX">$\mathrm {GF}(2^{q})$ </tex-math></inline-formula> is combined with adaptive <inline-formula> <tex-math notation="LaTeX">$2^{X}$ </tex-math></inline-formula>-ary digital modulations, which provides flexibility in diversifying modulation orders by mixing higher order modulations for initial HR transmission with a lower order for IR, it can improve performance in the low Signal to Noise Ratio regime. …”
