研究目的
Reviewing advanced modulation techniques for flexible optical transceivers and assessing their performance in terms of rate/reach trade-off.
研究成果
The paper concludes that all considered modulation schemes allow for a good granularity in terms of net data rate and transmission distance, albeit at the expense of increased complexity in DSP algorithms. The development of efficient but simple Tx and Rx DSP algorithms is identified as a key challenge for the cost-effective realization of flexible transceivers for next-generation optical networks.
研究不足
The paper discusses the technical and application constraints of the experiments, including the complexity of DSP algorithms for advanced modulation schemes and the impact of nonlinear propagation effects on performance. Potential areas for optimization include the development of more efficient DSP algorithms and the mitigation of nonlinear phase noise.
