[0085] In step S3, if both the first spectrum compatibility result and the second spectrum compatibility result are compatible, the first device at the first operating frequency and the second device at the second operating frequency are spectrum compatible; otherwise, they are spectrum incompatible.
[0086] Specifically, if the first or second device only transmits or only receives, the spectrum compatibility result is the result calculated under a single operating condition.
[0087] In step S5, the number of all operating frequency combinations is counted; the number of spectral incompatibilities among all operating frequency combinations is counted; if the ratio of the number of spectral incompatibilities among all operating frequency combinations to the number of all operating frequency combinations is greater than a predefined inter-frequency hopping device spectral conflict probability threshold, then the first device and the second device have a spectral conflict.
