Abstract

We proposed and experimentally demonstrated a trellis-path-limited sequence estimation method combining the log-likelihood ratio from minimum-mean-square-error equalizer-enabled signal detection with soft-decision -FEC decoding under severe bandwidth limitations, achieving 1.35-Tb/s 256-GBd 16QAM and 1.65-Tb/s 208-GBd 64QAM.

基于支持软判决前向纠错的网格路径序列估计的200gbd以上QAM信号检测

我们提出并实验证明了一种网格路径限制序列估计方法，该方法结合了最小均方误差均衡器支持的信号检测的对数似然比和在严重带宽限制下的软判决fec解码，实现了1.35-Tb/s 256-GBd 16QAM和1.65-Tb/s 208-GBd 64QAM。
