We examine reduction of phase jitter by use of in-line Butterworth filters in soliton systems in the context of differential phase-shift-keying coding. We also demonstrate numerically that the use of a Butterworth filter in a return-to-zero differential phase-shift-keying system can reduce continuum background radiation.
我们在差分相移键控编码的背景下，研究了在孤子系统中使用在线巴特沃斯滤波器来减少相位抖动。我们还通过数值证明，在归零差分相移键控系统中使用巴特沃斯滤波器可以减少连续背景辐射。
