Description

technical field

[0001] The embodiments of the present application relate to the field of communication technologies, and in particular to a method, device, electronic device, and storage medium for compensating AAU group delay fluctuations. Background technique

[0002] Active Antenna Unit (AAU) is the main equipment of a 5G base station and an implementation of a large-scale antenna array. AAU can be regarded as a combination of remote radio unit (RRU) and antenna, integrating multiple radio transceiver (T / R) units.

[0003] With the rapid development of wireless communication technology and the continuous upgrading of communication standards, the signal bandwidth becomes wider and wider. The widening of the signal bandwidth will affect some indicators of AAU hardware design, such as the in-band group delay fluctuation index. The wider the signal bandwidth, the worse the group delay fluctuation index. During signal transmission, if the group delay fluctuates greatly, the ...
