Protograph-Based LDPC Code Design for Probabilistic Shaping with On-Off Keying
, 2019 This work investigates protograph-based LDPC codes for the AWGN channel with OOK modulation. A non-uniform distribution of the OOK modulation symbols is considered to improve the power efficiency especially for low SNRs.

Ultra-Sparse Non-Binary LDPC Codes for Probabilistic Amplitude Shaping
, 2017 This work shows how non-binary low-density parity-check codes over GF($2^p$) can be combined with probabilistic amplitude shaping (PAS) (B\"ocherer, et al., 2015), which combines forward-error correction with non-uniform signaling for power-efficient ...
