A New 5-Bit/2D-Symbol Modulation Format for Relative Intensity Noise-Dominated IM-DD Systems
We propose a novel 5-bit/2D-symbol modulation format based on PAM-6 optimized for IM-DD systems dominated by relative intensity noise. The proposed modulation scheme improves SNR by 0.94 dB compared to conventional PAM-6 and achieves near-optimal BER performance. ©2025 The Author(s)
