Multi-Level Coding (MLC) was proposed by Imai and Hirawaki as a bandwidth efficient coded modulation scheme designed for protecting each bit of a non-binary symbol with the aid of binary codes, while maintaining different target Bit Error Rates (BERs). Parallel Independent Decoding (PID) is employed as an efficient decoding strategy with reduced decoding delay, where there is no information exchange across the different protection classes. Multi-Level Coding (MLC) invoking Generalized Low-Density Parity-Check (GLDPC) component codes is proposed, which is capable of outperforming the classic LDPC component codes at a reduced decoding latency.
