摘要
对使用了相位连续的频移键控编码方式(FSK)的信号传输系统中的几种传输信号现代检测方法进行了探讨,并对其所对应的信号特征的提取方法进行了数学描述;提出了应用各种通信信号特征提取方法的特征函数,为了可靠地应用各种特征函数,指出了其检测方法的使用方法;最后,对各种信号特征的提取方法进行了比较,得出了相应的结论。
Discusses the modern test method for the transmission signal in the signal transmission system with phase-consecutive frequency shift keying (FSK) encoded mode, and describes the relative signal characteristic extraction method with mathematics and presents the characteristic function for the communication signal characteristic extraction method. In order to use the characteristic function reliably, presents the application of the test method. Finally compares the extraction method of the signal characteristic, and gets the relative conclusion.
