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。
The phase modulation has some more advantages against CW, which USES ASK (amplitude shift keying).
相位调制与使用ASK(幅度键控)的CW相比有很多优点。
