Robust quaternary fountain codes in AWGN interference

IET Communications, 2018
Luby transform (LT) codes have received less attention in larger non‐binary fields. Robust soliton distribution (RSD) was designed to provide universal optimality over the binary erasure channel in terms of minimising the overhead.
