Abstract

This Letter presents a layered ternary message passing (LTMP) decoder for the low-density parity-check (LDPC) code tailored for 50G passive optical networks (50G-PON). The proposed decoder adopts a layered architecture, and a corresponding density evolution analysis that enhances error correction performance is introduced. Additionally, we propose an optimization method for parameter combinations, which effectively achieves stronger performance. Results indicate that the LTMP decoder achieves exceptional error correction capabilities for the LDPC code in 50G-PON, even under low-precision input conditions.

50G-PON中LDPC码的分层三元消息传递解码器。

本文介绍了一种分层三元消息传递（LTMP）解码器，用于为50G无源光网络（50G- pon）量身定制的低密度奇偶校验（LDPC）代码。该解码器采用分层结构，并引入相应的密度演化分析，提高了纠错性能。此外，我们提出了一种参数组合的优化方法，有效地实现了更强的性能。结果表明，即使在低精度输入条件下，LTMP解码器也能在50G-PON中实现出色的LDPC码纠错能力。

期刊介绍： The Optical Society (OSA) publishes high-quality, peer-reviewed articles in its portfolio of journals, which serve the full breadth of the optics and photonics community. Optics Letters offers rapid dissemination of new results in all areas of optics with short, original, peer-reviewed communications. Optics Letters covers the latest research in optical science, including optical measurements, optical components and devices, atmospheric optics, biomedical optics, Fourier optics, integrated optics, optical processing, optoelectronics, lasers, nonlinear optics, optical storage and holography, optical coherence, polarization, quantum electronics, ultrafast optical phenomena, photonic crystals, and fiber optics. Criteria used in determining acceptability of contributions include newsworthiness to a substantial part of the optics community and the effect of rapid publication on the research of others. This journal, published twice each month, is where readers look for the latest discoveries in optics.
