The embodiment of the invention provides a radiation source individual identification method, device and equipment, and relates to the technical field of communication, and the method comprises the steps: receiving a first modulation signal; performing enhancement processing on the first modulation signal to obtain a constellation diagram which is related to the first modulation signal and contains nonlinear statistical characteristics; inputting the constellation diagram into a target radiation source identification module, and outputting a classification result of radiation source individuals related to the first modulation signal; wherein the target radiation source identification module is used for identifying the category of the radiation source individual according to the nonlinear statistical characteristics contained in the constellation diagram. According to the scheme, the accuracy of individual identification of the radiation source can be ensured when the noise is relatively large.
Description
technical field [0001] The present application relates to the field of communication technologies, and in particular, to a method, device and device for identifying a radiation source individual. Background technique [0002] With the rapid development of wireless communication, wireless communication services are growing rapidly. In order to ensure the efficient and safe wireless communication, radio monitoring is required. Therefore, radiation source identification technology, as an intermediate step in signal reception and demodulation, is a technology that can quickly and automatically identify different radiation sources by analyzing the statistical characteristics of implicit non-ideal hardware fingerprints of received signals. [0003] The existing radiation source identification technologies are divided into two categories: likelihood-based modulation identification technology and feature-based radiation source identification technology. The former can obtain optim...
