高频的频率边带由于幅度交叠的部分较少，所以对强度起伏贡献较少。
The higher frequency sidebands would have less contribution to the fluctuation due to smaller amplitude overlapping.
结果表明，在堆积脉冲的强度谱中存在一系列分立的频率边带，这些频率边带对强度起伏有贡献。
The results show that there are several separated frequency sidebands in the intensity spectrum of the stacked pulse, responsible for the intensity fluctuation.
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。
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.
