ASK混噪信号的自适应消噪系统

ADAPTIVE NOISE CANCELLING SYSTEM OF ASK SIGNAL CORRUPTED BY NOISE

作者提出一种自适应消噪系统,对受强电干扰(宽带平稳过程)的ASK混噪信号有明显消噪效果。在分析消噪系统主要部件(平衡式自适应信号分离器及自适应波形识别检测器)性能的基础上,研制出硬件系统。经测试表明,该系统消噪效果明显。

The authors advance an adaptive cancelling system, whichhas evident cancelling effect on ASK signal noise produced by intenseelectricity.On the basis of analysing the property of the main parts ofcancelling system, balanced adaptive signal separator and adaptive waverecognition detector, a hardware system is developed. The test showsthe system with a clear effect on cancelling noise.
