subcarrier multiplexing

Moreover, with the introduction of microwave subcarrier multiplexing, coherent optical communication system is able to accomodate multiple users or multiple information bit stream simultaneously.

本文经过研究及仿真发现：相干光通信系统的性能确实优于非相干光通信系统，而且，通过引入光微波副载波复用方式，可以使相干光通信系统能够同时承载多路用户或者多种信息。

Thirdly, we quantify the power penalty caused by the PMD in optical subcarrier multiplexing ( OSCM) system with amplitude shift keying ( ASK) and binary phase shift keying ( BPSK).

第三，对采用不同调制格式（包括幅移键控和二进制相移键控）的光副载波复用（OSCM）系统中，PMD引起的功率代价进行了量化。
