[0049] In step S1, when the first device operates at a first operating frequency and the second device operates at a second operating frequency, the spectrum compatibility when the first device transmits and the second device receives is calculated to obtain a first spectrum compatibility result.

[0082] In step S3, if the first spectrum compatibility result and the second spectrum compatibility result are both compatible, the first device at the first operating frequency and the second device at the second operating frequency are spectrum compatible; otherwise, the spectrums are incompatible.

[0083] Specifically, if the first device or the second device only transmits or only receives, the spectrum compatibility result is a single working condition calculation result.

[0084] In step S5, the number of all operating frequency combinations is counted; the number of spectrum incompatibilities of all operating frequency combinations is counted; if the ratio of the number of spectrum incompatibilities of all operating frequency combinations to the number of all operating frequency combinations is greater than a predefined spectrum conflict probability threshold between frequency hopping devices, then the spectrum of the first device conflicts with the second device.

[0085] In some embodiments, a typical value of the predefined spectrum conflict probability threshold between frequency hopping devices is 30%.

[0086] In summary, the solution proposed in the present invention can clarify the spectrum compatibility status between the agile frequency device and the fixed frequency device and between the agile frequency devices, and provide an effective technical means for spectrum compatibility analysis of the agile frequency devices.
