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。

Concerning the problem of demodulating the weak Binary Phase Shift Keying (BPSK) signal, the demodulation method based on chaotic system was researched.

针对微弱二进制相移键控(BPSK)信号的解调问题，对基于混沌系统的解调方法进行了研究。
