[0040] The present invention will be further described in detail below with reference to the drawings and examples.
[0041] Such as figure 1 As shown, the processing steps of the method of the present invention are:
[0042] (1) The signal fingerprint device of the network access point monitors the steady-state communication signal transmitted by the individual communication device, and first extracts its conventional characteristics, including the carrier frequency, code rate and other individual characteristics that contain the attributes of the wireless device.
[0043] Conventional signal characteristics are the technical basis of the present invention, that is, part of the steady-state signal fingerprint. The latter refers to a regular change trend that is repeatedly shown in the signal transmitted by the same communication device during normal communication. The information on the change law of the signal has technical characteristics that reflect the individual characteristic...
