| 摘 要： | 通过对基于正交相移键控(QPSK)色散管理孤子(DMS)传输系统的研究,用变分法得出了孤子在互作用下各参数随传输距离演化的方程。频域导频滤波器加入QPSK色散管理孤子系统后进行了数值模拟,实现了系统的稳定传输,结果表明孤子相位随传输距离的增加并不影响系统的稳定传输。同时导频滤波器也抑制了相位的增加,提高了系统的性能,这在实际应用中具有重大意义。

| Abstract: | Based on a quadrature phase shift keying （QPSK） dispersion managed soliton （DMS） transmission system, including interaction between solitons, the evolution equations of soliton performance parameters versus distance are deduced by the use of the variational approach. By using the control method of frequency-guiding filtering adding in the system, the stable transmission is realized. From the numerical simulation, the increasing phase has no effect on stability. The frequency-guiding filtering suppresses the increasing phase and improves the system performance, which has huge weight in practical application. |
