摘要

在相干光学QPSK系统中实验研究了一种速率为0.83的非二进制准周期ldpc编码调制方案。对于I/Q良好平衡和高度不平衡的情况，都观察到较大的编码增益。通过增加BCJR均衡器的内存，成功地减轻了接收机带宽不足引起的性能下降。

An experimental investigation of high-rate nonbinary quasi-cyclic LDPC-coded modulation for coherent optical communication

A rate-0.83 nonbinary quasi-cyclic LDPC-coded modulation scheme is experimentally investigated in a coherent optical QPSK system. Large coding gains are observed for both I/Q well balanced and highly imbalanced cases. By increasing the BCJR equalizer's memory, degradation caused by insufficient receiver bandwidth is successfully mitigated.
