[0047] In step S1 , the minimum frequency point is selected from the frequency points of the first device as the first frequency point; and the frequency point with the smallest absolute value of difference from the minimum frequency point is selected from the frequency points of the second device as the second frequency point.

[0048] Specifically, the two devices are the first device and the second device, wherein the first device has m frequency points, and the frequency values ​​from small to large are [A1, A2, ..., A m ]; The second device has n frequency points, which constitute a frequency point set whose frequency values ​​are sorted from small to large.

[0049] In step S2, when the first frequency point is used as the transmitting frequency and the second frequency point is used as the receiving frequency, it is calculated whether there is electromagnetic interference between the first frequency point and the second frequency point to obtain a first electromagnetic interference result.

[0064] Specifically, the radiation power density S at the first device when the second device transmits is calculated as

[0065]

[0066] where P B is the transmitting power of the second device, and G B is the antenna gain of the second device. The interference power P r received by the antenna of the sensitive device is

[0090] The calculation of the interference matrix element values of all combinations in the first combination set according to the size relationship between the first frequency point and the second frequency point when the interference matrix element value is 1 further comprises:

[0091] When the second frequency point < the first frequency point, on the side greater than the second frequency point in the frequency point set of the second device, the interference matrix element corresponding to the next frequency point of the second frequency point is calculated, if the interference matrix element is 1, the interference matrix element corresponding to the next frequency point is calculated again, until the corresponding frequency point with the interference matrix element of 0 is found, the first right frequency point is obtained; the interference matrix elements corresponding to all frequency points greater than the first right frequency point are 0; on the side less than the second frequency point in the frequency point set of the second device, the interference matrix element corresponding to the previous frequency point of the second frequency point is calculated, if the interference matrix element is 1, the interference matrix element corresponding to the previous frequency point is calculated again, until the corresponding frequency point with the interference matrix element of 0 is found, the first left frequency point is obtained; the interference matrix elements corresponding to all frequency points less than the first left frequency point are 0.
