The Performance of CDMA approaches that of WDM, but it also faces some problems such as spectrum interference from multiple users and shot noise etc.
通常CDMA系统接近波分复用的性能，但是也面临一些有待解决的问题，例如多用户时的谱干扰、散弹噪声等。
Each optical signal propagating in the WDM optical communications system occupies its own wavelength within the gain spectrum of the optical amplifier.
每一个在WD M光通信系统中传播的光信号在光放大器的增益光谱内都占有其各自的波长。
Finally, when there were eight WDM optical input signals, using the black box model and two level model respectively, we simulated the amplified optical spectrum.
最后分别模拟放大系统采用黑盒模型和两能级模型，有八个WDM光信号输入时，放大后的光谱图。
