摘要
针对于实际应用中的小信号,特别是完全被噪声淹没情况下的微弱信号提取问题进行了论证,分析了信号和噪声在时间特性方面和统计特性上的差别,介绍了一种有效的用相关函数检测技术来提取被噪声淹没的极微弱信号的方法。
This papaer discusses the pickingup issue for those small signals in practice applications,especially for those delicacy signals,entirety submerged in yawp,analyses the differences betwween the signal and the yawp on the time and stating,and introduces a sort of effectual inspecting technology,using correlation function inspecting picksup of tiny delicacy signals,entirety submerged in yawp.
