adjusting the antenna to be adjusted to reduce interference on the antenna sequence group; and

controlling operation of an adjusted antenna sequence group;

wherein determining, according to the performance parameters, an antenna to be adjusted from the antenna sequence group comprises:

determining an antenna with orthogonality not meeting a requirement from the antenna sequence group as the antenna to be adjusted according to the performance parameter, comprising:

determining an antenna orthogonally mismatched with other antennas in the antenna sequence group as the antenna to be adjusted according to the performance parameters and the coordinate position of each antenna in the antenna sequence group; and/or

determining, from the antenna sequence group, an antenna orthogonally mismatched with a base station antenna as the antenna to be adjusted according to the performance parameters.

determining an alternative antenna for the antenna to be adjusted, and switching a radio frequency transceiving path originally communicated with the antenna to be adjusted to be communicated with the alternative antenna; or,

adjusting a radiation angle of the antenna to be adjusted.

5. The antenna anti-interference method of claim 4 , wherein determining an alternative antenna for the antenna to be adjusted comprises:

determining the alternative antenna for the antenna to be adjusted based on at least one of the performance parameters or a coordinate position of each antenna on the communication device.

6. The antenna anti-interference method of claim 1 , wherein determining, according to the performance parameters, an antenna to be adjusted from the antenna sequence group further comprises: determining an interfered antenna as the antenna to be adjusted according to the performance parameters and the coordinate position of each antenna in the antenna sequence group, wherein after determining an interfered antenna as the antenna to be adjusted according to the performance parameters and the coordinate position of each antenna in the antenna sequence group, adjusting the antenna to be adjusted comprises:

in response to an interference source being a directional interference source, determining a direction of the directional interference source with respect to the antenna to be adjusted; and

adjusting a feed contact of the antenna to be adjusted until a radiation direction of the antenna to be adjusted is kept away from a direction where the directional interference source is positioned.

7. A non-transitory computer-readable storage medium, storing at least one of antenna anti-interference programs which, when executed by one or more processors, causes the one or more processors to perform the antenna anti-interference method of claim 1 .

8. A communication device comprising a processor, a memory, and a communication bus, wherein the communication device further comprises a plurality of antennas;
