成功地实现了汉宁窗、高斯窗调制的任意频率单音频信号的产生，达到了任意波形发生器的功能。
The real arbitrary waveform generator that can generate single acoustic frequency signal modulated by Manning window and Gaussian window is developed.
特别是，当传感观测中存在高斯噪声或调制源时，往往无法获得准确的源波形恢复。
Especially, accurate restoral of sources waveform is often impossible when there are Gaussian noise or modulatory sources in sensor measurement.
在对高斯脉冲波形的时域和频域特性进行分析的基础上，采用直接序列扩频方式，进行脉幅调制产生超宽带信号。
Based on the characteristics analysis of the Gauss impulse in time and frequency domains, we generate the UWB signal by 2pam-ds modulation.
