Then we perform digital pre-compensation method, which can be used in the processing of base band signal to reject image frequency and protect carrier leak to meet the application purpose.

然后采用对基带信号的数字预补偿方法来抑制镜像频率和载波泄漏，从而达到应用的目的。

Then we perform digital pre-compensation method, which can be used in the processing of base band signal to reject image frequency and protect carrier leak to meet the application purpose.

其思路是将信号先通过单边带调制，将较低频率调制到需要的频率范围；然后采用对基带信号的数字预补偿方法来抑制镜像频率和载波泄漏，从而达到应用的目的。

Gaseous helium is used as a coolant during the drawing of optical fibers, as a carrier gas for chromatography, and as a leak detection gas in a variety of industries.

气态氦在光学纤维拉制中用作冷却剂，在色谱仪中用作运载气体，在许多工业中用作检漏气体。
