摘要
指出传统的数字反向传输方案对光纤进行补偿时不能得到系统的最小误码率,分析了不同反向传输长度对系统性能的影响。提出了基于最优传输长度的数字反向传输方案,并证明了在最优传输长度处能获得最小误码率。仿真结果表明,该方案能够提高系统性能。
The paper indicates that the system BER is not the minimum when the traditional digital back propagation（DBP） is used to compensating the optical fiber communication system, Analyses the influence of different reverse transmission lengths on the system performance. The paper proposes that the backward propagation is based on the optimal transmission length, and proves that it can obtain minimum bit error rate at the optimal transmission length. Simulation results proved that this scheme can improve the system performance.
