We seek in this paper to differentiate driven nonlinear systems using only a single output signal from the driven system. We do not have access to the driving signal. We demonstrate the phase space identification techniques with an experimental model of a radio transmitter. We restrict the driving signals to nearly periodic signals, because these types of signals are the most common signals used in real transmitters. We find that by studying our transmitter as a driven nonlinear system, we are able to distinguish one transmitter from another. This work may have consequences for real transmitters.
我们在本文中寻求仅使用来自驱动系统的单个输出信号来区分驱动非线性系统。我们无法访问驱动信号。我们使用无线电发射机的实验模型演示了相空间识别技术。我们将驱动信号限制为近周期信号，因为这些类型的信号是实际发射机中最常用的信号。我们发现，通过将我们的发射机视为受驱动的非线性系统进行研究，我们能够将一个发射机与另一个发射机区分开来。这项工作可能对实际的发射机会产生影响。
