Abstract

Probabilistic shaping (PS) as an effective method for approaching the Shannon limit further has got much attention nowadays. A novel chaotic sequence bit-operation based probabilistic shaping scheme is proposed in this study, and improvement in bit error rate and channel capacity is demonstrated experimentally. When the optical power is -12 dBm, the maximum bit error rate is improved by 3.61 dB compared to conventional 16-CAP. In addition, the generalized mutual information performance is ameliorated under low received optical power. And the feature of chaotic sequences, which will be further studied in the future, offers potential for improving safety.
