| 摘 要： | 基于光标记交换中的DPSK/SCM组合调制方案,分别仿真了SCM调制灵敏度、副载频和标记速率三个因素对DPSK信号性能的影响,得出副载波最佳调制灵敏度为0.3,最佳副载波频率的大小为净荷速率的一半或与之相等,且标记信号速率越高,净荷的接收性能越差.

| Abstract: | Based on a combined modulation scheme for optical label switching using DPSK/SCM,respectively stimulate the effects to the DPSK signal performance,caused by the SCM sensitivity,the frequency of subcarrier and the label bit-rate,find out the optimum value for the SCM sensitivity is about 0.3,the optimum value of the frequency of subcarrier is equal to the label bit-rate or half of it,and the higher the label bit-rate is,the worse the performance of detecting the payload signal is. |

| Keywords: | DPSK/SCM modulation sensitivity subcarrier frequency label bit-rate |
