Abstract

The embodiment of the invention relates to the technical field of communication, and discloses an AAU group delay fluctuation compensation method, which comprises the following steps: acquiring a first reference signal sent to a signal receiving device by an AAU and a second reference signal generated by the signal receiving device; determining a phase value of the delay fluctuation of the AAU group according to the first reference signal and the second reference signal; and compensating the group delay fluctuation of the AAU according to the phase value. The embodiment of the invention also discloses an AAU group delay fluctuation compensation device, electronic equipment and a storage medium. According to the AAU group delay fluctuation compensation method and device, the electronic equipment and the storage medium provided by the embodiment of the invention, the group delay fluctuation of the AAU can be effectively improved, the design of AAU hardware does not need to be changed, and the cost of the hardware design is not increased.

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 ...
