Adaptation of 5G NR LDPC-Coded Probabilistic Amplitude Shaping to 50 GBaud PAM4 Signals in IM/DD Bandwidth-Limited System
We experimentally demonstrate 50-GBaud probabilistically shaped PAM4 via 5G NR LDPC-coded PAS over 20 km in IM/DD bandwidth-limited system, achieving up to 2.6 dB receiver sensitivity gain over uniformly distributed PAM4 post-FEC decoding and IDM.
