Embodiment approach 1

[0058] Determine the signal strength of each channel collected in the current period, and set the signal strength collected in the current period as the signal interference level of the corresponding channel.

[0059] For example, there are three channels from channel 0 to channel 2, the signal strength of channel 0 is -20db, the signal strength of channel 1 is -15db, and the signal strength of channel 2 is -30db; In this way, the signal interference level of channel 0 is -20db, the signal interference level of channel 1 is -15db, and the signal interference level of channel 2 is -30db.

Embodiment approach 2

[0061] Determine the signal strength of the channel in the current period and the signal strength in the historical period, perform weighted calculation on the signal strength in the current period and the signal strength in the historical period, and obtain the signal interference degree of the channel.

[0062] Among them, this embodiment can select any number of historical periods. Here, two historical periods are taken as an example to illustrate the above implementation: there are two channels, channel 0 and channel 1. The signal strength of channel 0 in the current period is -20db, and channel 1 is in The signal strength of the current period is -10db; the signal strength of channel 0 in the previous period is -40db, the signal strength of channel 1 in the previous period is -20db; the signal strength of channel 0 in the previous period is -60db, channel 1 The signal strength on the upper cycle is -40db. The weight of the current cycle is 0.5, the weight of the previous ...

Embodiment approach 3

[0064] The weight of the preferred channel is reduced from an initial value to a target value; wherein, the preferred channel includes a boundary channel; the weights of all channels except the preferred channel are the initial values; according to the channel The product of the weight of and the signal strength determines the signal interference degree of the channel; wherein, the weight of the channel is positively correlated with the signal interference degree. The aforementioned boundary channel refers to the first channel and the last channel. For example, the channels of the first device and the second device include 0 to 36, and channel 0 and channel 36 are boundary channels. In practical applications, the border channel is less used and has less interference, so the weight of the border channel can be reduced to increase the probability of the border channel being selected as the target channel. Further, the above preferred channels may also include commonly used chann...
