キーワード:Coding and forward error correction for optical communications , Digital signal processing techniques for optical communications

We present a simplified log likelihood ratio (LLR) for LDPC decoding and compare the post-FEC BER performances of PS-16QAM in coherent optical communications systems. The improvement of post-FEC BER is 1.17dB for PS-16QAM.
