Performance Analysis of the LDPC‐Coded Hybrid LQAM‐MPPM for UWOC Systems

IET Optoelectronics, Volume 20, Issue 1, January/December 2026.
The effectiveness of LDPC codes in improving the performance of hybrid modulations is discussed, with coded 128‐QAM‐(12, 2) MPPM offering ~6.5 and 5.8 dB code gains at a BER of in strong and moderate turbulence, respectively. These results demonstrate the promise of hybrid modulation with LDPC as a robust and efficient modulation scheme for UWOC ...
