[0003]In the distributed antenna system, optical fiber is used for transmission between the host unit and the extension unit, and an analog feeder is used for transmission between the extension unit and the remote unit. Since the length of the feeder is different , In addition, the feeder material and manufacturing process will affect the feeder insertion loss. In order to make the index performance of each remote unit in each frequency band consistent, ensure the gain balance of the en

Abstract

The invention relates to a multi-frequency system gain self-adaption method and device, electronic equipment and a storage medium, and the method is applied to a far-end unit and comprises the steps: receiving a combined communication signal sent by an extension unit, extracting a first synchronization signal from the combined communication signal, adjusting an attenuation value of a first common attenuation module based on the first synchronization signal, and extracting a second synchronization signal from the combined communication signal, checking whether the attenuation value of the first common attenuation module satisfies a preset condition based on the second synchronization signal, and adjusting the attenuation value of the second common attenuation module based on the second synchronization signal when the attenuation value of the first common attenuation module satisfies the preset condition. Therefore, the gain adjustment operation is performed by using the existing synchronizing signal, the response time of the system is greatly shortened, the link gain adjustment is automatically and quickly completed, and the stability of the system link is improved.

Description

technical field [0001] The present disclosure relates to the field of communication technology, and in particular to a multi-frequency system gain adaptive method, device, electronic equipment and storage medium. Background technique [0002] With the large-scale networking of 4G networks and the gradual popularization of 5G networks, the advantages of distributed antenna systems supporting multiple frequency bands are becoming more and more prominent, and there are more and more applications. [0003] In the distributed antenna system, optical fiber is used for transmission between the main unit and the extension unit, and an analog feeder is used for transmission between the extension unit and the remote unit. Due to the different length of the feeder, the material and manufacturing process of the feeder will affect the insertion loss of the feeder. In order to make the index performance of each remote unit in each frequency band consistent, ensure the gain balance of the ...
