摘要
利用马赫-曾德尔外调制技术,提出了基于双二进制的光双边带-双二进制、光单边带-双二进制和光抑制载波-双二进制调制方案,并在光载无线通信系统中进行了传输性能分析.结果表明:光双边带-双二进制调制方案以高抗色散和抗非线性效应能力,在36 km以上的光载无线通信系统中表现出较好的传输特性.
Based on the Mach-Zehnder external modulation technology, double sideband-optical duobinary,single sideband-optical duobinary and optical carrier suppress-optical duobinary modulation schemes are proposed in radio over fiber (RoF) communication systems, and transmission performances of the three kinds of modulation schemes are analyzed. The results show that double sideband-optical duobinary has the best transmission characteristics for its anti-dispersion and nonlinear effect ability in RoF communication systems above 36 km.
