摘要
传统的八进制不能完美的调解键空光信号,因此马赫-曾尔延时利用检查模块的工作原理,对八进制的相移控制格式进行了改革。在这改革中,其改革方案非常有意义,能够将产差分八进制移到键控光信号中进行调解。之后采用调解方法对单信道中差分八进制相移键控调制格式中的色散和非线性传输性能进行分析研究。经分析研究结果显示其他低进制的调制格式的色散容忍度会低于差分八进制相移键控。其线性容忍度会比差分二进制相移键控和差分四进制相移键控,不过,普通的二进制幅度键控会比其要低。
traditional octal not perfect mediation key space optical signal,so mach-had Eyan use module to check the working principle and the octal phase shift control scheme for the reform of the. In the reform,the reform program is very meaningful,can produce differential shift keying to octal optical signals in the mediation. After the mediation method of single channel differential octal phase shift key control modulation formats in the dispersive and nonlinear transmission properties were analyzed. The analysis results show that the dispersion modulation format of other low band tolerance will be lower than the octal differential phase shift keying. Its linear tolerance can be compared with the differential binary phase shift keying and differential binary phase shift keying,however,the average binary amplitude of the four will be lower than its. own.
