spectral amplitude

Various spectral amplitude codes are studied for evaluation with respect to their performance against three noises namely shot noise, thermal noise and phase induced intensity noise ( PIIN).

为了评估抗三种噪声性能，即散射噪声、相位噪声（PIIN）和热噪声，本文研究了各种光谱幅度编码。

It can be seen that the improvement of threshold power obtained in experiment agree with theoretical research very well, and equal-amplitude spectral lines can improve the SBS threshold power in fiber transmission system.

理论和实验符合的非常好，证明了等幅光梳可以提高光纤光传输系统中SBS的阈值功率。
