| 摘 要： | 随着带宽需求的不断增长,多维多阶调制格式成为目前研究的热点.文章对8PSK(3阶相移键控)、8QAM(3阶正交调幅)和16QAM(4阶正交调幅)的实现方式从原理和拓扑结构上进行了综合性的比较研究.使用已商用的调制器件,通过串行或串并混合的结构配置,可以得到8PSK、8QAM和16QAM的调制光信号；而使用并行结构的配置...

| Abstract: | With the continuously growing demand for optical network bandwidths,multi-dimensional and multi-level modulation formats,such as 8PSK,8QAM,16QAM,have become a current focal point of research.In this paper,we make a comprehensive comparative analysis of the principles and topologies for the realization of these formats and obtain 8PSK,8QAM and 16QAM modulated optical signals by using commercially available modulation devices configured in a serial or hybrid structure.We can improve the system integration lev... |
